Comparison Between AAC Blocks and CLC Blocks

Comparison Between AAC Blocks and CLC Blocks

To answer the most common question people ask me, “should I manufacture AAC* blocks or CLC^ blocks?” here I am with the promised guide about comparison between AAC blocks and CLC blocks. I hope it helps my audience to decide the right product for them. I have tried to compare both products on various parameters. This by no means is an exhaustive list, but it might help to guide your decision making process in right direction. I’ll include some more parameters soon. Kindly go through it and let me know your views. I would be glad if this guide helps you decide on the right kind of lightweight block. So here is first episode in comparison between AAC blocks vs CLC blocks.

Note: Kindly post your CLC related queries on our discussion forum. I have set up a dedicated topic to deal with CLC blocks and related queries. This would be like one stop solution for anybody looking for information related to CLC blocks.

1. Production capacity

Generally production capacity of CLC blocks ranges from 20 to 80 m3/day. This relatively small capacity is result of various factors which I have discussed below. In case you want to ramp up production, then there is very little you can do other than replicating the manufacturing line.

Production capacity of AAC blocks starts from 160 m3/day and goes all the way up to 1500 m3/day depending on client requirement. But most of the plants in India have production capacity in range of 500-1000 m3/day. For those who want to set up their first AAC plant, I would recommend 350-500 m3/day as initial capacity. Of course it can be scaled up later on without much hassle and little bit of extra investment. Going for capacity smaller than 350 m3/day is not advisable as there is very small difference in terms of investment since except for extra autoclaves; rest of the equipment stays the same.

So, if you are looking for a expandable project with bigger volumes, then AAC blocks manufacturing is the one for you.

2. Scalability

As most of the CLC equipment is available in lower capacities, ramping up production would require setting up a parallel line. In addition to investment, it would also call for more manpower. Moreover like other cement products, CLC requires a total curing time of 28 days, more space would be required to accommodate increased production. Since CLC blocks require such long curing time, they can’t be stacked up unlike AAC blocks to save space.

It is possible to increase production capacity of AAC plant just by installing more autoclaves and some extra molds. As a matter of fact most of the equipment for plant capacity from 160 m3/day to 800 m3/day is same except for number of autoclaves and molds. These factors work in favour of AAC as production capacity can be increased with much lower investment. AAC is the clear winner in this section.

3. Land requirement

CLC equipment requires very less space due to compact size and smaller production capacity. A CLC production facility requires around 350 m2 of covered space (depending on automation levels) for protecting CLC equipment from the elements. But much more space is required for curing CLC blocks. As mentioned earlier, total curing time for CLC blocks is 28 days. Out of this, wet curing is required for minimum 14 days. Moreover since ‘green’ CLC blocks can’t be stacked above each other beyond a certain limit, lot of space is required. E.g. A CLC plant producing 50 m3/day would require minimum space of 1400 m2 to accommodate 28 days worth of blocks arranged in stacks of 1 m3 (1 m x 1 m x 1 m) each. Similarly if production is increased by 25 m3/day, space requirement would increase by 700 m2.

On the other hand, AAC factory with production capacity of 500 m3/day requires around 5 acre (20,000 m2) of land. AAC blocks are ready to be used once they are steam cured inside autoclaves. Due to this AAC blocks can be stacked on top of each other without worrying about any damage. This way no additional space is required for finished goods storage even after capacity expansion. Even while expanding the capacity of an AAC plant land required does not increase drastically. E.g. scaling up from 160 m3/day to 240 m3/day requires less than 400 m2 of space.

4. Investment

CLC equipment with production capacity of 20 m3/day ranges between Rs. 2-5 million depending on the supplier and level of automation. Project cost for a 20 m3/day plant would come to around Rs. 3.5-7 million excluding land. Since total production and hence sale of a CLC plant is lower, working capital requirement is smaller.

Equipment cost for AAC plant of 500 m3/day would range from Rs. 50-80 million for Chinese equipment depending on the supplier and level of automation. Similar capacity equipment from European vendors would cost anywhere between Rs. 400-700 million. Most of the AAC machines in India are of Chinese origin, so we’ll continue keeping that in mind. Project cost for a 500 m3/day plant would come to around Rs. 130-200 million excluding land. In addition to high project cost, working capital required for AAC plants is much higher due to bigger production capacity.

In terms of investment, AAC is clearly the most capital intensive project and recommended for those with strong funding sources. While for those entrepreneurs who want to make smaller investment and test waters, CLC is the way to go.

5. Manpower

A medium capacity CLC plant of 40 m3/day would require 6-10 workers in a shift (8 hours), bringing total manpower requirement to 18-30 workers per day.

An AAC plant of 500 m3/day would require 12-15 workers in a shift (8 hours) with total manpower requirement to 36-45 workers daily.

      • Sir I want to start a acc plant in a small scale in visakhapatnam. Can you please tell me the process,details from where I can get the machinary and the total cost to set up the plan.what steps should I take while starting up?

          • Dear Harsh,

            I am afraid it won’t be possible for you to share a detailed project report with you as each project report is designed to suit client requirements. Moreover since it has been funded by respective client, it it their intellectual property (IP) and hence I am bound to respect their IPR.

        We are planning on establishing an CLC plant of a capacity of 100,000 cbm. We came to this decision since we have a land of about 7 acres.
        First of all, I was hoping if you could tell me the difference between AAC and CLC in terms of strength. Which one shall a prospective customer by to make his home walls strong.

        Also, as we know that there is a 28 days curing process, what I was in doubt was if the storage place needs to be covered ?

      • Sir,
        I have come across a thought of setting up CLC or/and AAC block plant.Please advise how feasible is it in South Gujarat.What would be the project cost and is it a viable project to go for with Bank borrowings

      • Dear Pravin,

        Thank you for your response on my website. Strength alone becomes a very broad parameter. It is usually considered together with density. Let me know what density you are looking at so that I can share strength parameters for AAC blocks vs CLC blocks. Moreover, there is a huge variation in strength of CLC blocks depending on manufacturers. Similarly strength of AAC blocks also varies between different manufacturers.

        we are planning to start the CLC plant in Bangalore,
        Please help me in setting up the plant and guide on quality factor.
        What are the parameters that will affect the quality and how to improve, how to minimize the production cost.

        • Dear Sridhar,

          Thank you for your response on my website. I do not have experience setting up CLC block units, but I may be able to throw some light on critical parameters that will create a good standing for you in this market.

          1. Focus on quality and not profit margins. Once your name becomes synonymous with quality, people will willingly pay more for your products.
          2. Ensure that all processes are adhered to religiously. Any small oversight can affect quality of the final product.
          3. Ensure proper curing. Proper curing will require sprinkling water at regular intervals for first 2 weeks of curing process.
          4. Dispatch best of the lot. Dispatch only good quality blocks and avoid dispatching blocks with cracks or chipped off corners. A good amount of breakage takes place during handling. See to it that you minimize that amount.

          These factors will not only create a good and strong image for your products in the market, but will also increase your returns over a period of time.

          Regards,

          Vishal Kansagra

        • Dear Sridhar

          Getting quality product out of the factory requires quality machinery, good understanding of the CLC technology and having a right consultant to help you in case you are stuck with any issues after you start production. We too had faced issues time to time, but we were able to solve the issues with the right expertise we had access to and didn’t had production delays. If you have already purchased machinery, ask for assistance in getting quality blocks from the same person. If any issues, you can post it here.

        • Dear Ritesh
          What’s your strength and density requirement ? how much cement is consumed for getting the strength you specified? based on that I may help you.

          Kash

          • Dear Kash,

            the strength we have attained for 800 is 18-20Kgs/sqcm. OPC Cement 300, Fly Ash 150, Sand 300. Water 23 Ltrs and superplastisizer 0.5 Ltr per 50 Kg cement.
            For 1000 density we have gotten a strength of 22-25 Kg/cm2. OPC Cement 350, Fly ash 150, Sand 450, superplastisizer 3.5 ltrs for 1CM, 7 bags cement.
            Please help so that we can attain a strength of 25+ for 800 Density and 35+ for 1000 Density.

  2. I would like to know whether setting up a new ACC unit of approx 500 m3/day in kolkata wud be a viable proposition

  3. Dear Sir,

    We are into government construction enplaned with Military engineering services & Assam Rifles offices in Dimapur & Guwahati. We are planing to go for fly ash brick plant including interlocks, pavements etc. As in process we came to know about AAC blocks and as there is no AAC blocks plant in north-east it seems a good proposition.

    Request your suggestion on this and how to go about.

        We are interested in making a CLC plant near indore. Can you send more details or call me.

      • I am sorry Sir.I want to question for you.
        I want product AAC(autoclaved Aerated concrate) a small scall or hume industry,but I have problem about Autoclaved.wich one the price too expensive.and no size small.
        naw,whoud you exsplain to me,about way work of Autoclaved?

        and is one series Autoclve by chamber? or no.

        how way or metod the autoclav has hight pressure,temperature ?

        • Dear Zamzami,

          Thank you for your response. For more details about autoclaves you can refer to http://en.wikipedia.org/wiki/Autoclave . Usually the autoclaves used for AAC industry have a diameter of 2-2.8 mtr and length of 26.5-38 mtr. Rated temperature and pressure is in range of 150-200 C and 1.2-1.6 bar respectively.

          I wouldn’t recommend trying to build your own autoclaves as it is a separate industry altogether. Moreover AAC plant requires heavy investment, so I doubt whether it can be treated as small scale industry. Instead of going for AAC, you can try for CLC as it does not require very big investment in terms of capital cost and working capital.

    • i wish starting Light weight bricks manufacturing in a humble way. Kindly suggest the consultants/turnkey contractors

  4. Hi,
    Congrats for the great site…
    I had quite a few questions for CLC blocks manufaturing. I want to setup a CLC plant near new delhi to cater to some of my clients there. I too have this dilemma of CLC vs AAC. So here are my questions:

    1. As far as the quality is concerned, How does CLC compare to AAC and how does it affect the end consumer perception when he is to make a choice?
    2. What are the price points at which CLC and AAC blocks sell in the market?
    3. How to go about setting up this plant? What all needs to be considered before making that investment?
    4. Any ideas on why are these blocks not getting enough traction in domestic market i.e. when an end consumer buys bicks to construct his house.
    5. Any ideas on selecting the location of plant to be setup.

    I know that I am asking for a lot of information but whatever information you can provide would help me a lot. Thanks in Advance

    • Dear Rahul,

      Thank you for being a dedicated follower. I have got your queries and will definitely try to answer them. Just give me some time as I am busy traveling across India. Once I am back, I’ll definitely try to answer all your queries. And don’t worry about consulting charges, CLC is not my cup of tea and I don’t dabble with stuff that I am not good with. :)

      Regards,

      Vishal Kansagra

      • Dear All ,
        as far as the quality is concerned in clc we need to take care of the compressive strength,
        the weight (i e density) , the aesthetic look or the dimensional accuracy.

        when we compare between clc and aac i think , we should visualise that the only difference is the raw material and the curing process rest all is same.

        we dont invest more on the premix so we cant reach higher capacities in clc, where as you have a complete premix setup in aac.

        clc made in the best possible manner can be comparable to aac.

        vishal i am liking this portal of yours , never thought about it .. well i have been working on flyash related products flyash bricks , clc and now aac .since 2005 , and have been manufacturing machineries too.

        good work

          Greetings of the day! I am interested in setting up a CLC plant near Karimnagar, AndhraPradesh. May I know your contact details. I would like to go for semi automated and wire cutter machine.

          Warm Regards,

    • Dear Rahul

      my self friend of Mr. Vishal and i am in clc consultancy field since few years and he has invited me to this thread to answer query about clc.

      Have gone through your query about CLC vs AAC and will try to give your ans related to this query

      1. As far as the quality is concerned, How does CLC compare to AAC and how does it affect the end consumer perception when he is to make a choice?

      when we take about quality concerned in CLC you can achieve various strength and density as per the requirement of customer and In CLC you have various application apart from block. and when it comes to customers perception that which to choose among AAC or CLC i think this is not time for that because still AAC and CLC both are in their starting phase and as per my vision to market every customer has its own dilemma about any product which to choose. and also depend on your service and quality you offer. so both will work here in surat we have three plant of AAC and 20 plant of CLC every one is getting their part of market.

      2. What are the price points at which CLC and AAC blocks sell in the market?

      For the price point it mainly depends on the local market it changes every state to state and even city to city for example in Chennai CLC and AAC both selling price is round 3700 to 4000 and in Bangalore it is 4500 to 4700 so selling and costing price point is depend on local raw material availability and their price and also make much difference on transportation too.

      3. How to go about setting up this plant? What all needs to be considered before making that investment?

      first of all consider your targeted market place and find near by thermal plant and check their fly ash quality and availability for the same and for CLC their are various plants available in market imported and from local manufactures too and this is all depends upon your available budget and always try to go with good plant offering best foam generator, mixture and foaming agent as this is very important for start up because in CLC manufacturing as you learn you can reduce the costing of blocks with your experience gain.

      4. Any ideas on why are these blocks not getting enough traction in domestic market i.e. when an end consumer buys bicks to construct his house.

      As i have mention above that this is just starting of CLC and AAC in India so will take time for consumer to adopt it. As in our city due to non availability of blocks builders do wait for blocks. so this is matter of time but in future every one will use this blocks due to their lots of benefit.

      5. Any ideas on selecting the location of plant to be setup.

      As per our suggestion location of plant should be not so far from available raw material and your targeted market because main cost adding factor for the blocks is transportation.

        • Dear Raunak,

          Thank you for your response on my website. I am afraid I won’t be much help for CLC blocks plant as I do not deal with CLC plant.

          In order to study the market, you need to talk to builders, architects, structural engineers as well as contractors to see how receptive they would be to such a product and understand their perceptions about the product. In case such products are already available in market, try to visit construction site using such products and talk to users to see what benefits and challenges they perceive from these products. This would give a good idea about market and usage and help you adapt and plan accordingly.

      Thank you for your response. I have got your queries and some more queries about CLC. I will definitely try to answer them. Just give me some time as I am busy traveling across India. Once I am back, I’ll definitely try to answer all queries regarding CLC blocks and AAC blocks.

      Regards,

    • Dear vishal modi

      my self friend of Mr. Vishal and i am in clc consultancy field since few years and he has invited me to this thread to answer query about clc.

      Have gone through your query about CLC vs AAC and will try to give your ans related to this query

      1. As far as the quality is concerned, How does CLC compare to AAC and how does it affect the end consumer perception when he is to make a choice?

      when we take about quality concerned in CLC you can achieve various strength and density as per the requirement of customer and In CLC you have various application apart from block. and when it comes to customers perception that which to choose among AAC or CLC i think this is not time for that because still AAC and CLC both are in their starting phase and as per my vision to market every customer has its own dilemma about any product which to choose. and also depend on your service and quality you offer. so both will work here in surat we have three plant of AAC and 20 plant of CLC every one is getting their part of market.

      2. What are the price points at which CLC and AAC blocks sell in the market?

      For the price point it mainly depends on the local market it changes every state to state and even city to city for example in Chennai CLC and AAC both selling price is round 3700 to 4000 and in Bangalore it is 4500 to 4700 so selling and costing price point is depend on local raw material availability and their price and also make much difference on transportation too.

      3. How to go about setting up this plant? What all needs to be considered before making that investment?

      first of all consider your targeted market place and find near by thermal plant and check their fly ash quality and availability for the same and for CLC their are various plants available in market imported and from local manufactures too and this is all depends upon your available budget and always try to go with good plant offering best foam generator, mixture and foaming agent as this is very important for start up because in CLC manufacturing as you learn you can reduce the costing of blocks with your experience gain.

      4. Any ideas on why are these blocks not getting enough traction in domestic market i.e. when an end consumer buys bicks to construct his house.

      As i have mention above that this is just starting of CLC and AAC in India so will take time for consumer to adopt it. As in our city due to non availability of blocks builders do wait for blocks. so this is matter of time but in future every one will use this blocks due to their lots of benefit.

      5. Any ideas on selecting the location of plant to be setup.

      As per our suggestion location of plant should be not so far from available raw material and your targeted market because main cost adding factor for the blocks is transportation.

  6. I understand that you might be a bit busy but kindly see if you can find some time to answer some of my questions on CLC (as posted above). If you provide consulting services for setting up such plants, I will be more than willing to go for it.

    • Dear Rahul,

      Thank you for being a dedicated follower. I have got your queries and will definitely try to answer them. Just give me some time as I am busy traveling across India. Once I am back, I’ll definitely try to answer all your queries. And don’t worry about consulting charges, CLC is not my cup of tea and I don’t dabble with stuff that I am not good with.

      Regards,

      Vishal Kansagra

  7. Vishal your guidance on the AAC vs CLC is quite good but it lacks product comparison.
    I shall appreciate if you could give us an insight into it. Thanks in advance.

    • Dear Anand,

      Thank you for appreciation. I’ll try to do a product comparison between AAC blocks and CLC blocks. It is a tough call considering the fact that configuration changes as per suppliers. And since there are large number of suppliers when compared to AAC suppliers, it gets even more exciting. For benefit of product comparison, I have procured some CLC blocks and AAC blocks and have sent them for testing. Once I get the results, I’ll update them on my website.

      Regards,

      Vishal Kansagra

  8. Dear sir,
    I want to setup an AAC BLOCK project in Nagpur. Please advice about its feasibility regarding potential nmarket. Also i want to know more about the complete process include step by step guide. Please help with costing.

  9. Thx for talking on phone, someone asked you that he was having difficullty in competing on price with aac blocks as comparered to his clc blocks, is it true that clc will always be more expensive to produce vis v aac blocks, i am related to Koncept Ambience people in Hyderabad, they say that it is heavier and water absorbtion problems exist in clc blocks.

    • Dear Manish,

      Thank you for your response. I’ll try to answer your queries point by point.

      1. Will CLC blocks always be more expensive than AAC blocks?

      Higher cost of CLC blocks can be attributed to higher cement content (25-40%) and foaming agent. Cost of foaming agent varies from Rs. 130-250 depending on origin and quality of foaming agent. Similarly, quantity of foaming agent required varies from 1.5-2.2 kg/m3. These two ingredients lead to higher raw material cost. When compared with AAC, raw material cost of CLC is much higher. This difference in cost is offset to an extent by lower overheads of CLC production compared to AAC production. But even after that cost of 1 m3 of CLC is higher than that of AAC.

      2. Weight and water absorption issues with CLC blocks.

      Density (weight) and strength of CLC blocks can be controlled by altering the recipe of CLC production. In fact in that regard CLC offers more flexibility by allowing blocks of various density and strength to be produced as per requirement.

      In addition to recipe, factors like strength and water absorption are also dependent on how well CLC blocks are cured. If recipe is not right and blocks are not cured properly, then weight, compressive strength and water absorption issues might crop up.

      You may also visit forum to discuss about CLC blocks in detail under topic titled ‘CLC blocks and related queries’

      Note: I don’t have production experience with CLC blocks, but I have knowledge of it as a product in class of lightweight concrete just like AAC.

      Regards,

      Vishal Kansagra

  10. Dear Vishal

    Thank you for providing the details on AAC and CLC on your web site. I just wanted to understand as to what is the main difference between AAC/CLC vs Fly ash brick. Is CLC and fly ash brick same?

    I would be interested in setting up a plant on AAC in the eastern part of India (either WB or Orissa). Pls guide me.

    Regards
    Sandeep

    • Dear Sandeep,

      Thank you for your response. You question in itself calls for a detailed article highlighting differences between AAC blocks, CLC blocks and fly ash bricks. It would be really kind of you if you may give me some time to put together an article on this topic.

      I’ll send you an email regarding setting up AAC plant in Eastern India.

      Regards,

      Vishal Kansagra

    • Dear sandeep

      my self friend of Mr. Vishal and i am in clc consultancy field since few years and he has invited me to this thread to answer query about clc.

      Their is no basic difference between clc and aac both are same product from physical structure and light weight as fly ash bricks are with out any compound agent to make them light weight so they are just heavy bricks it also heavier then red bricks while clc and aac both are very light say 50% lighter then red and fly ash bricks.

  11. dear sir,
    how to reduce cost clc blocks.our cost clc blocks 3100 per m3.and market price aac block 3200 m3 FOR jodhpur. our plant is in bhilwara. rajasthan.
    can we use lime and gypsum replace cement in clc blocks.

    • Dear Deepak,

      Thank you for your queries. As I mentioned earlier, I don’t have production experience with CLC blocks, but I have knowledge of it as a product in class of lightweight concrete just like AAC. So allow me to get someone with CLC blocks production experience to advice you on production issues related to CLC blocks.

    • Dear deepak

      my self friend of Mr. Vishal and i am in clc consultancy field since few years and he has invited me to this thread to answer query about clc.

      I think this is very high costing you are getting so first of all you have to give me how much material you are using for the 1m3 and what is the price of raw material you are getting and then let me know about your plan foaming agent and foam generator too and their ratio with water you use so after getting all this we can see why you are getting so much of costing and will try to reduce the same

      • Dear Mr. Nilpesh,
        We have been into light weight concreting since a long time but were doing only in-situ castings. We have a production capacity of 150 m3 per day which includes foam generator, mixer, dispensing pump which can pump the material directly to the moulds.
        Recently we’ve got an order from a reputed builder in Delhi-Ncr to produce CLC blocks for them at their site. Their criteria for the CLC blocks is density not more than 800-850 kg/m3 & strength not less than 3.5 mpa/mm2. We are using class 1 pond ash from the Dadri NTPC Plant & the design mix for the same is as under:
        Cement: 250 Kg.
        Flyash: 250 Kg.
        Water: 150 Liter.
        Foaming Agent: 1:40 Ltr. protein based
        Lime Water: 20 Ltr.
        Hardner: 1 Ltr.

        Kindly suggest if the design mix is right to attain the desired results because while doing trials for them we happened to achieve these results one or two times but are not getting it constantly. The trials were done in cubes whereas we are trying to authenticate ourselves by doing the same in proper mould size of 500x200x250 being stacked vertically in the height of 500. Moreover we also intend to cure the day’s production in a steam curing chamber for 18 hours so that we can despatch the days production on the third day. We have developed a steam curing chamber based on the principles of Autoclave chamber. Kindly suggest something to improve to achieve the desired results regularly.
        Please reply ASAP as the client has already started setting up the production area to start the production immediately & we are waiting for the proper results to come up before investing in the moulds & steam curing chamber.
        Thanks & Regards,

    we made clc block 900-950 density.
    can we replce cement and use lime.
    please replay soon.

    • As per IS 2185, CLC density requirement is 800 kg/cbm and compressive strength should be minimum of 2.5 N/mm2. So guys, pls make sure the above important parameters are maintained when manufacturing CLC blocks.

      As per IS 2185, Density requirement for AAC blocks can be from 450-550 kg/cbm with compressive strength of 2 N/mm2.

      In hyderabad market, AAC blocks are manufactured around 600-650 kg/cbm density and around 3-4 N/mm2 strength. Where as CLC is around 800 kg/cbm and around 2.5 N/mm2 strength.

      By looking at density, you can understand that about 150 – 200 kg less material is required for manufacturing of AAC blocks. Even though the setup costs are high for AAC plant, one can go upto 500-1000 cubic meter per day production capacity. This results in less overall manufacturing cost for AAC block. The highest capacity of CLC plant in India as per our knowledge is around 70 cubic meter per day (manpower requirement and land requirement is much higher in this case).

      Market acceptence of AAC blocks is much higher than CLC blocks even though the selling cost of CLC blocks is always 300-400 Rs per cubic meter less than AAC blocks. Current AAC market price is around 3400-3600 Rs/cubic meter, CLC market price is any where from 2800 – 3100. This is because of the following points.

      1. CLC blocks is heavier than AAC block. (4” AAC block weight is 7.5 kg, CLC block weight is 10.5 to 11 kg).

      2. The edges/corners are easily damaged in clc blocks because they are naturally cured and to reach their maximum strengh it takes around 3 months. we normally deliver the blocks in 3 weeks time.

      3. AAC block looks much better (yes, looks are important to builders it seems!!!).

      4. Yes, water absorption is very low in CLC blocks (around 10-12 %) compared to AAC blocks (around 20-25%).

      You can try reducing about 50 kg of flyash and 30-50 kg of cement and check the strength of the block. This will result in density of the block to 800 kg/cubic meter compared to your 900 kg. How much power is required for your CLC plant? our electricity cost per cubic meter is around 60-70 Rs. We are using about 1.2 liter foaming agent per cubic meter.

      you can contact me for more information.

  15. Hi Vishal,

    I am planning to construct a residential house in Bangalore. I have a request for you on CLC & AAC. Is there any supplier for these blocks in Bangalore? I spoke to many Residential building contractors they are not aware of these product and in fact they are on backfoot to use these products. I have gone through many websites but could not find a confident contractor.

    My requirement is Stilt + G + 2 around 4000 sq.ft of floor area including stilt. I would like to know is CLC or AAC panels can be used for floors (instead on concrete)? Is there anyone manufacturing Wall/floor panels near by Bangalore ? Apart from quick construction is there any savings on cost of construction?

    Many thanks,
    Subramanya C R

  16. Sir
    your page is very informative and helpful to all those who are interested in clc blocks
    I am manaf from Cochin ,Kerala in to building construction for the last 10 years. Recently I came to know about clc blocks and its possibilities .In our place due to the high price and non availability of clc blocks we still use conventional clay bricks and cement blocks for the constructions, also came to know that clc blocks are available in all sizes in different densities for different uses and the cost will also vary according to the densities and size. Can u please tell me the approximate production cost of 1 cu.m of 6” thk block with density of 1200 kg/m3? Is there any way to reduce the cost of production? Can we use sand as a substitute of fly ash?
    I am very much interested in this product and would like to set up a unit in tamilnadu .I may get the wet and fly ash at the cost of 900 and 1750 rsptvly from nearest plant 200km away from my site. Is it viable to start a unit .I am in bit confused about the cost of production and the marketing.
    I request your valuable suggestion whether to go ahead with this project.
    Waiting for your guide line

  17. Sir,

    I have seen all the differences between CLC blocks & AAC blocks but not about durability of CLC bocks and AAC blocks. Please let me know. So that we can explain to customer to sell good product.

  18. I have started a new clc plant recently a month back, but i am facing lot of problems to get required end product, where i am using flyash obtained from a paper mill boiler (fine black wet powder).
    But i am not getting the desired result, slurry is not setting within 15 hours, edges are damaging while demolding, water absorption is high, bricks doesen’t float in water but sinks in water, colour is dark black. I am using animal protein based foaming agent, colour is dark brown. And i am using OPC 43 grade cement.

    My query is 1) The flyash i am using is not appropriate one or is it ok?
    2) is there any alternate to flyash like stone crusher powder, granite polish residue(fine powder), sea shell residue sand(with salt content), etc.,
    3) is there any binding chemical for fast setting of slurry?

  19. sir, can we use lime replace cement in clc block. and can we use clc blocks load bearing in normal low rise building.

    • No do not use Lime in CLC blocks. You can try a mixture of cement, sand, flyash in various proportions.

      Lime is used in AAC blocks because they are cured using autoclaves. CLC is naturally air/water cured.

      For load bearing you need to produce higher density/strength CLC blocks. obviously the production cost of this is high compared to normal 800 density blocks.

      • sir, can we make clc blocks 1200 density for load bearing.and can we make clc blocks normal size bricks like 9/4/3.because we belong ruler area.there is no response for light weight blocks.demand only load bearing bricks. because already running red clay brick plant in our area approx 300 plant.and rate of clay bricks 4rs per bricks.how can we compete with clay bricks?

        • Your production cost goes up to produce 1200 density block because you need to add more flyash and cement. If you produce 9/4/3 clc blocks, don’t you lose one of the main benifit of clc block? Just educate people/builders about clc product. Challenge them that builder can complete brick work at same rate or less by using clc blocks, compared to red brick.

  20. Hi Mr. Vishal.

    First of all, thanks for all the valuable info.
    I am planning to establish a AAC manufacturing plant in Maharashtra.

  24. Hi All,

    Benefits of Foaming Agent in Manufacturing of CLC:

    Tremendous weight reduction
    High thermal insulation
    Optimum fire rating
    Substantial material savings:
    • no gravel used
    • little cement
    • less steel in structure and foundation
    • Easy and fast production
    • No primary energy and reduced transportation costs

    CLC, like conventional concrete ages well, increasing its strength by as much as 50% (!) between 28 and 90 days after pouring, As long as CLC draws humidity from the atmosphere it will keep on increasing its mechanical properties.

    Generally Manufacturer of CLC block import this foaming agent from Gulf countries, German etc.
    Because of which its cost increase by many folds.

  29. Dear Nilpesh sir, i want to know the proportion of raw material to make clc block ranging density of 800. Please guide me.

  30. Dear Mr. Vishal

    I am planning to set up AAC plant near yamunanagar. I have a few queries for the same:

    Initially, I need to know about the quality of the fly-ash required. The thermal here is shut down at most times but we have plenty of ash avialable in ponds that can go on for years. So we will be depending on pond ash mailnly. Though there is another thermal at a distance of 100kms so we can get fly ash from there. Will it be feasible.

    Also, what will be the difference in quality of the end product if I use the pond ash and grade D or grade E fly ash. Will the machineary also change if I have to use pond ash.

    And do you have any market knowledge of chandigarh and near-by areas and the potential of this product there.

  31. sir ,
    I would like to set up an AAC Block factory near pune so I need your cunsultation for the same ..so I wish to get in contact with you ..so plz reply on my mail add…

Which one should I go for? There is no guidelines wrt outer wall thickness here. as aresult most of builders are going for 4″ brick wall. In this case whether AAC/CLC will get reception, it is doubtful. The cost is another big factor for the builders.
    I have read all of comments on your website and found to be very useful.

    You can send me a mail if you like.

      i have the same doubts.if you have got the answers can you please forward them to me.
      thanks and regards.

      • Dear Ojas,

        Thank you for your response. Before going in to more details about AAC or CLC please let me know what is the investment you have in mind.

        Project cost for a 20 m3/day CLC blocks plant would come to around Rs. 35-70 lakh excluding land. While project cost for a 500 m3/day AAC blocks plant would come to around Rs. 13-20 crore excluding land. So decide accordingly and I’ll give you necessary information.

  50. hi vishal sir,

    i am a final year civil engineering student actually researching on the topic of CLC.i know your field of specialisation is AAC but im confident you could guide me in the following query.
    one of my friend has a small CLC plant near the outskirts of Pune.the capacity of the plant is 20m3/day production.
    After the bricks are casted it takes around 10-12 hrs to set in the open air (there is no shed).after they have set and attained enough strength to be walked over on they are kept for curing for 15 days ( 3 times a day cured with water,using pipe)

    i have 2 questions.
    1.how do i reduce setting time of these bricks of 10-12 hrs?
    2.how to reduce curing time from 15 days to say 8-9 days ?

    also,the weight of a 650x250x150 brick is 16-16.5kg…
    how do i reduce this weight ? do i use any different admixture or mix proportion ?

    please respond whenever you get time,i would be grateful if i get assistance from an expert like you.

    thanking you,
    ojas joshi

    • Hi ojas
      I am not clc block consueltant.I am manufacture of clc block.I can help u for my experience. if u reduce setting time u can use hardner.but your cost of blocks will be increase.
      and if u reduce weight of block u will have to reduce your wet density.

  51. Hi,
    I have been following this website for sometime now and without a doubt Vishal and Nilpesh deserves huge congratulations.
    After following this site for sometime, differences between AAC and CLC are quite clear.

    I don’t come from a construction background and hence i am having a hard time analyzing the market in my area.

    I have following questions
    (1) For a construction of around 10,000 sq feet of following structure can someone give me a rough idea how many standard size bricks (9 × 4¼ × 2¾ in) are required

    3 Story home
    3 Story Shopping Complex
    Open space, 4 walls, ceiling. Height equivalent to 3 story bldg.

    10,000 sq feet
    ?
    ?
    ?

    (2) Second question i have is, price point wise how does AAC block compares with clay brick. I understand AAC rate differs by area and more so clay brick. I am considering setting up AAC plant in Harda, madhya pradesh (Indore and Bhopal are major cities close to Harda for consumption).

    In the meanwhile i will investigate retail price of clay brick, cost of raw materials for AAC.

    Mr. Vishal i am highly interested in getting a consultancy from you on this project.

  52. Mr Nitin the basic thumb rule for the No of bricks required per sq ft construction area is 10 for residential building. Hence you shall require approx 1 Lac bricks for 10,000 sq ft built up area OR you can also calculate the total wall area and multiply it by 4.5 bricks per sq ft. for your other requirements.

    I am very impressed by this website. I am in the Business of Manufacturing of Fly Ash Bricks and in the process of setting up a new plant for the manufacturing of CLC Blocks at Guwahati. As per the best of my knowledge the major advantage in CLC is low water absorption and for AAC is low cost of production.

    But end of the day, foamed concrete is the immediate future for building blocks as approx 40% dead weight of a multistory building is due to bricks which can be reduced by half by using CLC blocks, saving in the RCC costs to the builder and recurrent savings to the occupier in cooling/heating costs.

    The problem in Assam is that Fly Ash is not locally available and we need to transport it from at-least 700 Kms away. What is the option of reducing the cost by using other materials like sand, stone dust, etc. Pond ash has very high content of silt, hence not very suitable.

    Hats off to you Mr Vishal…………..

    • Dear Ritesh,

      Thank you for your response. I am really impressed by the amount of research you have put in.

      But I would like to correct you about future of AAC and CLC. Due to high volume and lower production cost, AAC will take over the market. Because when you say reducing the dead weight, it doesn’t matter if a builder uses AAC or CLC as he’ll save weight by using either.

      In case fly ash is not available, you can use river sand, which I believe is easily and abundantly available in Assam.

      Thank you once again for your appreciation.

      Regards,

      Vishal Kansagra

  53. hi vishal,
    plz send me information about aac plant .
    cost of plant ,where to get machinery from,installation.

  54. Dear Vishal

    The entry level for AAC factory is very high compared to CLC. Also the high water absorption of AAC is negative for its use?????

    The problem of using river sand vs fly ash is that river sand the bulk density is around 1.50 and for fly ash is 1.00. Will this not effect the weight of the finished block?

    Also I would like your professional opinion – Is steam curing advisable for CLC blocks and is there any ill effects later on.

    • Dear Ritesh,

      Thank you for your response. Desired density can be achieved by changing ratio of raw materials and drawing up a suitable mixture. Density of the raw material should not be a major problem if you adapt your mixture accordingly.

      I have heard mixed responses about steam curing and due to lack of experience with CLC blocks, I would not want to comment on the same.

      Vishal Kansagra

    • Dear Ojas,

      Stop misleading people. You are just 5 posts old and forget about being friends, I hardly know you. And since when did you start consulting for CLC blocks? All I saw from you were posts asking ME about issues with CLC production.

      If you want to participate in discussions, then be decent about it. Don’t try to masquerade as my friend and misleading people. There are special provisions in IT Act 2000/2008 under section 66a. So try not to get in trouble.

  63. i amin manufacturing of clc blocks
    if you want to diiferentiate between aac/clc i will prefer you clc if its owner driven . wheae as aac if its employe driven . as in clc you cant find a satisfied customer due to different densities per blck but in aac its doest vary .

    • This is the most important difference between aac vs clc and it is not easy to discover. Thanks for pointing it out.

      I am inclined to think future goes to AAC because of this very important reason. Quality control of CLC is difficult and going to get worse due to lack of labour and skilled workforce.

  64. Dear Vishal,

    This is a very informative article. Thanks for that.

    I have some queries, it would be very kind of you if could answer them:

    1. Could you provide me update regarding the market scenarios of aac and clc blocks. Their price in
    Bihar.

    2. Is production of flyash brick different from aac blocks and clc blocks

    3. In production of flyash brick, is autoclaving necessary and what are the advantages of autoclaving. If
    yes, what does a machine cost?

    4. Can AAC clocks and flyash brick be manufactured with the same machine?

    5. What is estimated investment needed for setting up a fly ash brick manufacturing plant producing
    50,000 bricks a day.

    I know that I am asking for a lot of information but whatever information you can provide would help me a lot. Thanks in Advance

    • Dear Harsh,

      Thank you for your response on my website.

      I’ll try and answer your queries below:

      1. I am completely clueless about market scenario for AAC and CLC blocks in Bihar.

      2. Fly ash bricks, CLC blocks and AAC blocks are three completely different lines of business and have different production set up.

      3. Autoclave curing is not required for fly ash bricks. Autoclave curing is used to bring down the curing time.

      4. AAC blocks and fly ash bricks require completely different equipment.

      5. I don’t have any experience with setting up fly ash brick plants, so it would be better if you check with vendors supplying fly ash brick equipment.

      Regards,

      Vishal Kansagra

    I am in nashik and want to set up a new clc project is it feasible as of now or there are too many competitors today want to know.rest all I have studied the project well but only thing worrying me is wherther there are many suppliers for the same or a few????

  66. sir ,
    i want to know that if i manufacture CLC bricks and after all process complete i auto claved that bricks so what is your opinion.

    regards
    Ankit Goel

  67. Hi All,

    We want to set up CLC plant near Kolkata. We were little apprehensive about CLC becauuse of its appearance. Now with steam curing and wire cut process, i think that the CLC blocks will be more marketable and we can manufacture with increased capacity. Density of 900 – 1000 kg/m3 should not be a problem to achieve in CLC. Please let me know whether my line of thought is correct.

  69. can you tell how aac excels over clc and conventional clay bricks from an end customer angle. 2. what are the basic tests and results one has to look into before using such materials.

    • Dear Subash,

      Thank you for your response on my website. I am amazed by your query I believe you and your organization should be better placed to advice on such matters. I understand that you guys are already manufacturing AAC blocks under Renacon brand. I am pretty sure that your concerned department must have done enough research about differences between AAC and CLC blocks and advantages of each product. If that is the case then why do you need inputs from my side. I am not trying to shoot you down or anything, it is just my curiosity.

      Thank you for your response on my website. I am amazed by your query I believe you and your organization should be better placed to advice on such matters. I understand that you guys are already manufacturing AAC blocks under Renacon brand. I am pretty sure that your concerned department must have done enough research about differences between AAC and CLC blocks and advantages of each product. If that is the case then why do you need inputs from my side. I am not trying to shoot you down or anything, it is just my curiosity

      Regards,

      Thank you for your response on my website. I am a consultant and DO NOT represent any equipment vendors. I charge my consulting fees to my client and don’t work like AAC brokers floating around. I offer entire gamut of services ranging from selecting the right location to building marketing network for finished products. It is really up to you to decide what services you want to utilize.

      • Dear Vishalji,

        I Have CLC Plant from past 1 and Half year and faced lots of problems due to poor quality of machinery and Lack of technical knowledge of suppliers. I have been cheated by very famous ( ? ) Supplier.

        My problems were quiet common in CLC plants. like …

        Strength Issue ( Cannot fight with AAC Blocks in Market )
        Mix Design
        Water : Cement Ratio
        Foaming Agent ( I have tried many costing from Rs 40 to 250 Per Kg. ! )
        Density Variations
        Cutting Process ( Not cutting at bottom after wirecut )

        We see 85% of CLC Plants are shut down and people lost their investments. Only because of their less study on project and poor selection of supplier.

        To Survive I have spend lots of time, money and Sleepless nights to solve problems and wish to share my experiences with Plant owners And who are interested in setting up plant.

        It’s my humble try to save people from getting stuck after investing huge money.

        Thanks for giving platform to express my feeling and chance to save people from suffering.

        • Dear Silica Sand India,

          We are in the process of setting up a Clc manufacturing unit in guwahati and I request that you share your experience.

          Ritesh

        • making clc block is highly technical field and need to master the all aspects related to raw material , equipment , cement fly ash chemistry , water harndness & organic impurities , need changes according to different climatic conditions , foaming agent and foam generators to produce foam with low drainage and highly stable bubble formation.

          In indian tropical condition you need to be much aware than clc produced in cold countries.

        • Dear sir,
          i have clc plant with capacity of 20m3 per day for past 7months,we making clc blocks density between 800/850kg/m3.block size 500*200*200/150/100 with vertical mould type.we use grade-1 flyash,53grade opc,silica sand,fiber,protein based foam 1.33 per cum. water curing period is 15 days and next 5 days blocks will be kept dry condition with out sprinkling water.At 20 day we had done a compressive strength of 4 Blocks,from the same lot,the result was not even it was like 2.3/1.8/2.1/1.25 where dry density was not done,kindly suggest why there is an variation of strength between the blocks which was from the same lot,and also suggest that what is the correct testing procedure of CLC blocks.

    • Dear Nipun,

      Thank you for your response on my website. I have mentioned elsewhere and would reiterate here that I don’t have manufacturing experience related to CLC blocks, so I may not be the right person to advice you on same. But if you have any queries related to AAC plants, feel free to discuss them.

  72. Dear Sir,

    One of our clients has CLC plant. The drying of blocks takes longer because the plant is in Gurgaoan (Very cold during winters) surrounded by agricultural farms (adding to humidity).
    Can I suggest them forced air circulation? without affecting the quality.

    • Dear Bhupal Singh,

      Thank you for your response on my website. Force air circulation might work. But this would be just patching up. Ideally you should have designed recipe for your clients in such a way that this problem would not arise.

      Regards,

    • May be you can think of Steam curing…… it will work definitely. i have faced lots of problems due to drastic change in atmospheric temperature. have worked out some simple solutions to control consistency of production.

  73. Resp. Vishalsir,
    I am interested to establish AAC/CLC plant near Jamnagar (Guj).is it viable ? Please guide me .

  74. Please share some information on usage benefit of AAC over CLC as well as Clay bricks in terms of cost. I hear – Coloumn and beams can be lean, thermal conductivity is less, therefore saving on power (AC cooling) etc. more carpet area. Is there any detailed working that you can share ? will be really grateful.

  75. Dear Mr. Vishal Kansagra

    It was nice to see this kind of forum with continous disciussions & i appreciate you for answering to the queries posted.

    I am from Vijayawada, Andhra pradesh. I am planning to start a fly ash blocks manufacturing plant and i am confused whether to opt for AAC blocks or CLC blocks. Based on my market study, i came to know that there is a huge potential and market for this kind of blocks in our region. They are some queries regarding this.

    1. what type of blocks manufacturing is economically viable?
    2. Can you please provide me details of technology suppliers or Original Equipment Manufacturers
    3. How far i can create awareness among the people to adopt them to use the Fly ash blocks
    4. what are the practical problems encountered when going for fully automated process.

    I hope you will take me out of the confusions.

    Thanks & Regards

    • I may help you…. to select cutting technology…… i have tried experimented with many types of cutting machines . such as wire cutting by machine / manual, Band saw. Circular saw etc. each type is having it’s own Pros and Cons.

      many suppliers are giving demo of cutting machines live by cutting a cube. but know one knows what happens next day while unloading blocks from mold base ( Trolley ) .

      and be careful about selecting plant and machinery and SUPPLIER. 85% CLC Plant are closed due to these two reasons. I was also been cheated . But now I have survived and my plant is running with quality production. . and wish to help everybody who has been cheated and who are willing to start plant.

      Thanks

      • Dear Slica and Sand,

        I am planning to establish CLC plant at Jabalpur MP, as you are correct most of the plant machinery supplier are not up to mark.

        I want to have your valuable views/suggestions on machinery and plant for a plant 20/40 Cbm per day.

        Which vendors are good ? whether Automatic or semi automatic plant is good as fly ash is light and it will be settling every where on plant machinery.
        What abt after sales servicing and support from plant machine vendor supplier.

        Also i want to know Block cutting machines Vs Molds, which is better.

        Thanking you !

        Rgds,
        Anoop

        • Dear Anoop

          Please take into account, how many machines the supplier has supplied. Ask for contact numbers of plant owners, go and visit them by your self and make sure that you are satisfied with the machinery and the owner’s experience. This will give you confidence regarding the same. We can help you in procuring machinery and after sales service.

          We have our own CLC plant from last 3 years we are manufacturing about 20 cbm per day. We also supply CLC machinery and foam/hardner.

          There are not many issues with manual/moulds based CLC plant, except its a laborious process. Since technology is upgrading fast, you may adopt to cutting machinery etc. But moulds process is PROVEN, if you have immediate order of CLC blocks from a builder, then start a small capacity plant and then expand later on with moulds or block cutting machine. Except moulds, your other machinery will not change which ever the way you choose to go later on.

          hope this helps.

          Kash

  85. Dear Praful Ji,

    Wire cutting is not very effective for CLC blocks as far as I have seen practically. Moulds are a better option but space and capital intensive.

    Ritesh

  86. Hello Vishal,

    since there is such confusion between the costs of AAC and CLC, could you please suggest the right composition of material for AAC bricks with 650 kg per cu. m. density and for CLC bricks with 800 kg per cu. m. density?

    Also suggest how the composition should be varied in both the technologies to change their densities, hence strength.

    Thank you.

    • Dear Parit,

      Thank you for your response on my website. What you are asking is very specific information and hence beyond the scope of discussion here. It would require a detailed study of raw material samples and analysis of the same. I can help you if you are willing to pay for it.

      • hello Vishal Sir

        I found your side and saw that many peoples are taking guidance and grate sport from your side. seriously your guidance and way of talking with other people on ur side is vary nice and i like it. today i call you also but you can’t hear me. msry for inconvenience. Now shortly i want to say that i am doing work of contraction and interior designing with my father and now i want to start my individual business also so m thinking about the plant clc or aac blocks because i got a offer of large project of blocks from a malty national contraction company group of india. he offered me to supply clc and aac blocks from my side(Rajasthan) at dehli and gujrat in there project side. Sir i want to ask you that can i start a work of aac or clc blocks plant to complete these project ? because this project is >200-300cr. Actualy i do’t have any knowledge about production of blocks. but i want to start my personal and individual work also which is matching with my past work (contaction and interior designing) and this project is good chance for start my work. plz give me good guidance 4it. right now i can invest 5to7lac in new business so it is enough for plant of cement acc n clc blocks or not ?.

        Sir plz provide me your good help and some detail about aac and clc blocks.

        Sir company’s demand in blocks is good density and strength. which is in below of line.

        In clc blocks they required a density of 800kg/m3 and minimum compressive strength of 3.5n/sqmm and

        In aac blocks they required a density of 650-750 kg/m3 and compressive strength of 4.0 n/sqmm

        sir can you guide me about it that how much part of all martial like cement, concrete, ash, dust, cellular,….. for blocks i must to involve so that i can find nice density and strength in compare of company,s demand.

        please to be kind enough to look into my issues sympathetically and give me good guidance and sport so that i can start my work carefully.

        Thanks
        Regards
        Manmohan

        • Dear Manmohan,

          Thank you for contacting me. I went through the information you sent me. I understand that you have contacts to help you supply AAC/CLC blocks to 200-300 cr project. I also understood that you are willing to invest Rs. 5-7 lakh for the same project.

          I am afraid that investment of Rs. 5-7 lakh may not be enough for an AAC plant. This investment ‘might’ be enough for a small scale CLC plant. But then again the quantity produced at such a small CLC plant may not be enough to supply to the project you told me about.

          I would like to suggest that you capitalize on your contacts with the project. You can start sourcing it from AAC/CLC vendors and supply it to the project you told about. This way your exposure in terms of financial risk will be reduced to a great extent.

          In case of any doubts, feel free to call me.

    I have been going about your site for the past 2 hours now and I am really impressed. Thanks a ton for the free DETAILED info. that you’re providing. Its great to see and something that we rarely see these days….kudos to you for that..
    I have a query too.. :D I’m looking at setting a AAC plant in Siliguri in West Bengal and would like to know the feasibility for the region. As Siliguri is the gateway to the east of India it holds a strong market position catering to the hills of Darjeeling and Sikkim and locally of course. One of the major hurdles in using AAC I find here is that when queried about it developers here are reluctant to move away from the norm. that is clay bricks and use AAC bricks. Also cost becomes a factor too for many as we dont have DLF and other such big companies here who would prefer to use them.
    Thanks and much appreciated.
    Saurav

    • Dear Saurav,

      Thank you for your response on my website and your appreciation. I have done some rough calculations and found that AAC blocks in Siliguri sector might work out. You’ll need to use sand instead of fly ash as fly ash would be very expensive in your area. You can target markets like Guwahati. I believe AAC blocks are supplied in Guwahati by a company with a factory at Calcutta. You’ll need to do more research on your part as you are based there and would understand local dynamics better than me. :)

    Praveen

    • Dear Praveen,

      Thank you for your response on my website. CLC is a good product but due to lack of proper ecosystem and guidance, it has received a bad name. It would be a good idea to set up a CLC plant for your own consumption. This way you can control the quality as well control the costs. CLC slurry can also be used to cast entire walls rather than using CLC blocks to construct a wall. This would save your money in terms of time, labour and mortar.

      I hope this information has been helpful.

    We are planning AAC Block set up near Pune. Request you to send us more details.

    We are also in dilemma to whether go for AAC or CLC blocks? We have talked with some of our builder friends and got mixed results about the quality of CLC.

    with best regard
    Hasmukh Patel

    • Dear Hasmukh,

      Thank you for your response on my website. It is possible to set up a manual AAC block plant. But I don’t know how you’ll manage without sizing (cutting machine). IF you don’t use cutting machine, you’ll require individual moulds. Now handling these moulds prior to steam curing would be a very challenging task.

    • Dear Rhishikesh,

      Thank you for your response on my website. Strength of 6.5 N/mm2 in 725-750 kg/m3 density class doesn’t seem possible for AAC blocks or CLC blocks. It might be possible to achieve it in 1000+ kg/m3 density class.

    • Dear Pratik,

      Thank you for your response on my website. Since your requirement is around 3000 m3/year, it comes down to around 10 m3/day. This is too small to set up an AAC plant. You might want to think about setting up a small CLC blocks operation for your organic needs.

    • Dear Mano,

      Thank you for your response on my website. It may not be possible for me to share recipe or ‘formula’ on an open platform like this. These processes are bread and butter not only for me, but for many other professionals working in field of AAC blocks / CLC blocks production. Proportion of raw materials for AAC/CLC production is achieved after lot of testing and trials. Moreover it is not possible to suggest a formula just like that without analysis of required raw materials.

      In case of any other queries, feel free to interact.

  112. which type of curing req for the clc brick??
    dose any chemical have to add in cement morter for bonding of birck?

    • Dear Sumit,

      Thank you for your response on my website. Ideally it is better to go for water curing for CLC blocks, but it is also possible to steam cure CLC blocks. Your capital expenditure might increase if you opt for steam curing as you’ll require boiler and autoclaves.

    we use OPC and corse sand and 10mm down stone chips for or concrete mix on ratio of 1:1:2 and use steam curing and gain strength upto 300 plus in 72 hrs.
    Can CLC ar AAC technique replace our mix and get the desired strength.
    This will definitely give us added edge over the weight of our product and easier workability.
    What is the foaming agents used and it’s ratio to be used with fly ash and cement and the cost for it? Does it decreases the strength of the stablizing agent or not? Please let me know.

    Thanks for the comment on the same

    Piyush

    • Dear Piyush,

      Thank you for your response on my website. To be honest small scale plant won’t be viable in Rajkot or Hyderabad. There are couple of reasons for it. Rajkot has at least 2 x 100,000 m3/year plants withing 70 km radius. Total consumption of Rajkot is around 500 m3/day. This means there is already spare capacity in Rajkot even if we don’t consider AAC blocks from manufacturers based at Ahmedabad, Baroda and Surat. Knowing the market scenario in Gujarat as I do, prices have been slashed drastically and operating margins are getting thinner by the day. If you opt for a small scale plant, your operational expenses in terms of Rs./m3 will be high affecting final price of your product. This is due to minor difference in CAPEX and fixed costs. Due to higher price, your profit margin would be extremely low.

      Hyderabad has somewhat similar situation. So my suggestion is that you go for an optimum capacity plant to survive in this market.

        We can advise you in the following areas before you choose to buy machinery.

        - Suggestion of raw materials and bringing down production cost based on the availability of raw materials in your area.
        - Production cost based on the raw materials available in your area.
        - Solving production issues in reasonable time.
        - guiding you on marketing the product.

  130. Hi Vishal,

    I am based out of Kota, Rajasthan and want to start a CLC/AAC manufacturing plant. Have been looking for some consultants to help me on the same. I have scoped the area and raw materials like fly ash and cement are easily available, however I am a bit unclear of their adoption in domestic market here (have had discussions with some builders/architects in the area, they are skeptical about using big blocks….they are comfortable in blocks the size of regular clay bricks which I believe will negate a big plus point of this product increasing the total cost of construction. Additionally, some other conceptions /misconceptions which might be a roadblock for them to adopt it). Initially I was planning to go the CLC way but some research has put me in a state of confusion. I do not have a construction background, so the production will NOT be for consumption in any self projects. I did some research of my own but believe I need professional assistance before making my choice (my research has been more on the CLC side and am looking into AAC option after hearing a few drawbacks of going into CLC production…not sure how much of that chatter has weight to it). It would be great if you can send me details that you may share for an AAC project and also if we can get in touch to discuss the prospect/viability in this region plus technical drawbacks of the product. The investment I am looking to put in is around 1 Cr excluding land, which I guess is not enough for an AAC project; I was hoping we could discuss this in detail which might help me pick my poison. Also ‘if needed’ can you point me to a contact who I can consult for details on CLC project.

    Regards
    Nikhil

    • Additionally, I read few comments from CLC plant owners sharing their bitter experiences. I would appreciate a lot if they can spare some time to brainstorm so I may avoid such situations. Not sure if I am allowed to share my email ID or contact here so we can get in touch!

    • Dear Nikhil,

      I understand your concerns. Usually architects and engineers who are not familiar with such products try to stick to conventional products as they don’t want to jeopardize entire project. I believe things will change in areas around Kota soon as a 1,000 m3/day AAC plant is coming up in that region. I can’t give out specific details at this time, but it is expected to achieve commercial production in next 4 months.

      Investment that you are talking about is not sufficient to set up an AAC plant. My suggestion is that you take up a distributorship for AAC blocks in your region. This will give you ample exposure and idea about what is preferred walling material. With multiple plants coming up in NCR and existing plants in Gujarat, getting a distributorship may not be a problem.

      Regards,

  132. We are constructing an individual house in hyderabad,can you please suggest which brick is good CLC or AAC Blocks as we are completely new to this.

    • Dear Ramu,

      Thank you for your response on my website. I would suggest using AAC blocks for your home.

      Regards,

      Vishal Kansagra

      • IMO For individual house, AAC density of 650 kg/m3 with strength of 3+ N/mm2 may not be sufficient in terms of securing the house. For ground floor, consider solid bricks or light weight blocks (CLC/AAC) of 9 inch. For first/second floors CLC/AAC of 6 inch also is fine.

        CLC and AAC blocks have almost the SAME properties except few differences.

        CLC is usually 800 kg density, AAC is around 600-650 kg density. So this is a plus point for very high rise buildings.

        At the same time Water absorption is only 10% for CLC blocks, vs 20-25% for AAC blocks. This is a huge plus for CLC blocks for external walls where water seepage can be effectively controlled.

        • Dear Kash,

          3+ N/mm2 is sufficient for a load-bearing structure in G+2 configuration. My suggestion is to go for 9 inch wall for ground and first floor and 6 inch for second floor is fine. Electrical and plumbing lines also need to be kept in mind while deciding wall thickness.

          Regards,

          Vishal Kansagra

          • I agree that structure wise 3+ N strength is enough. But in terms of thieves digging up the wall, and so on…I was suggesting solid bricks with lot more strength. But at the same time you lose the benefits of light weight blocks if you go for solid bricks.

            So if your house is in gated community with proper security in place, even for ground floor you can go for AAC/CLC.

          • I doubt that. Breaking a wall is a noisy affair. It doesn’t matter if it is made from clay bricks or AAC blocks. It can be eventually broken. An easier way to gain access would be to break the locks rather than a wall.

  133. i suggest CLC with the below listed advantage
    Advantages of CLC Bricks
    • Low thermal conductivity.
    • Thermal Performances 5 times better than clay bricks & 10 times better than RCC
    • Interiors remain cool in summer and warm in cold wintry days.
    • Savings in recurring energy costs in air-conditioning.
    • Good Sound Insulation
    • Savings in recurring energy costs in air-conditioning.
    • Reduction of Dead Load
    • 1/3rd the density of clay bricks.
    • Economic design: savings in cement and steel.
    • Enables faster construction.
    • Suitable for low-soil bearing capacity & seismic zones.
    • Facilitates construction of unplanned walls any where anytime.
    Fire Protection
    Enhances Carpet Area
    • Better finishing of walls offers good amount of reduction in paints.
    • Eco-friendly.
    • Speedier Constructions.
    • Ease of Work ability.
    • Universal Acceptability.
    • Low Water Absorption

    • Dear Tushar,

      Thank you for your response on my website. I have tried to answer your queries below:

      1. CLC blocks can be steam cured. Although steam curing option will increase capital cost required for boiler and autoclaves. You’ll also need to add cost of steam production. In favour of steam curing, your production cycle from mixing raw material to delivering final product will become much faster.
      2. Since I do not deal with CLC and I do not have experience working in that domain, it may not be possible for me at this stage to suggest any vendors for turnkey solution for CLC blocks.

Primary factor is availability and cost of such walling material. If you are in an area with reasonable temperature fluctuation and are building a house not higher than G+2, lightweight blocks like AAC blocks or CLC blocks might work out to be more expensive. This is due to higher cost and negligible advantages offered in such structures. But if you are in a region where there are big temperature variations, it would be recommended to go for energy efficient products like AAC or CLC. Moreover if your house is bigger than G+3, you’ll off-set higher acquisition cost by lowering your project cost due to savings in steel and cement required for the structure. In addition to this, there will be life-long benefit of savings in heating/cooling costs.

      I hope this information helps you make the right decision.

  152. Dear Mr.Viishal

    Today only I had the opportunity to go through this website. Really useful and informative one. My kudos to you for your efforts.

    We have put up a unit for manufacture of CLC in Coimbatore , the first one in this area. As usual faced lots of hurdles in getting the right quality of material to compete / convince the market. We have been successful to some extent.

    We have silos for both cement and flyash. If we have to convert ours to AAC with an economical capacity , what is the additional investment in machinery required.We have already enough land and power .Kindly suggest.

    Some points to Mr.Niplish.

    1.How can the compressive strength increased – now its 2.5N for a density of 800 kgs/cbm.

    2.How can the density reduced from 800 to 700

    3.What is the hardener that we can use and how much

    4.kindly suggest some good suppliers of veg based foaming agents

    Thanks and Regards

  159. Dear Vishal,

    I had been through the whole thread but i have a diff question then others. i’m the end user viz i’m a builder i wanted to knw how it would be cost effective to me in precise terms if i use AAC instead of the regular fly ash. if you have a cost comparative sheets for me to knw that where do we save.we get a fly ash standard brick for rs 2.90 per piece and one cubic metre o fAAC at 3500/- (600mmx200mmx75-300).

    Warm Regards

    • Dear Shekhar,

      Thank you for your response on my website. Kindly let me know what kind of structure are you talking about here? Are you looking at G+2 houses or high-rise apartments? If you are focusing on cost saving for high-rise apartments, by using AAC blocks you can bring down cost of cement and steel required for structure. I am sure you are aware of the fact that AAC blocks have density of 600-650 kg/m3 while that of fly ash bricks is around 1400+ kg/m3. By using AAC blocks, you actually decrease dead weight of the building allowing you to save on structure. In addition to that there are savings in terms of cement and sand required for mortar as well as plaster. Moreover AAC blocks offer superior thermal and acoustic insulation which is not delivered by fly ash bricks. As you can understand there are lot of tangible and intangible variables involved when discussing AAC blocks vs fly ash bricks.

      I hope this information has been helpful.

  165. Dear
    We don’t have fly ash here which one is suitable for making block either ClC or AAC not using fly ash.

    • Dear Nirmal,

      Thank you for your response on my website. If fly ash is not available, you may use sand for manufacturing AAC blocks provided sand is easily available and at reasonable price. You’ll require ball mill for grinding purpose. Mind you it may not work out for a smaller project due to high initial cost and recurring cost of ball mill.

  166. Hi Vishal,

    We want to start a plant for CLC/AAC bricks. Do we need to get any approval from anyone to start this plant. Could you please let me know the details ASAP.

    Thanks in Advance,

    • Dear Sridhar,

      Thank you for your response on my website. Approvals will vary between AAC/CLC project. But general approvals required will be Non-agriculture conversion, local pollution control board, etc. For specific list of approvals, you can contact your CA as usually CA have right contacts to get your various approvals.

  169. Hey,

    Can you guide me with –
    1] Is their currently demand for ACC blocks from builders ?
    2] Is ACC blocks cost effective for builders over CLC or Red bricks or fly ash bricks in practicality?
    3] What is the current market price of ACC blocks in comparision to CLC ?
    4] SIPOREX produces a brick from wastage of their ACC blocks.
    Where can be the application of such brick?
    5] Should i use ACC blocks or Red bricks for my residential bungalow project?

    • Dear Rahul,

      Thank you for your response on my website. I have tried to answer your queries below:

      1. Demand is related to availability. So yes there is demand for AAC blocks in regions where AAC blocks are available nearby. Of course there are exceptions as well. But overall builders are very open when it comes to using AAC blocks as it reduces overall project cost.
      2. It is not possible to answer these question without considering location and cost of all products in the equation.
      3. Again, location makes a difference as there are around 40 AAC plants but many more CLC plants spread across India.
      4. Kindly let me know size of this rectified bricks. If it is conventional 9″ x 4″ x 3″, then I think breakage will be little on the higher side.
      5. Frankly using AAC blocks in bungalows of G+1/G+2 using beam-column structure, does not spell great savings for the builder. But it offers lower consumption of electricity for cooling/heating purpose for the occupants.
