Advantages of AAC blocks
Advantages of AAC blocks are varied and many depending upon local condition. Some of those advantages from India’s point of view are mentioned below:
Autoclaved Aerated Concrete blocks are about 50% lighter than clay bricks of equivalent size. This translates into less dead weight of buildings and allows entire structure to be lighter therefore reducing amount of steel and concrete used in structural components like beams, columns and roof/floor slabs.
Autoclaved Aerated Concrete is very easy to work with and can be cut accurately reducing the amount of waste generated.
Single Product Solution
Buildings constructed with AAC blocks do not require separate insulation products reducing construction cost, energy footprint and environmental impact of buildings.
Manufacturing of AAC blocks and panels does not have high energy requirements. Moreover since AAC is light weight, it also saves energy required for transportation and leads to reduced CO2 emissions by transport vehicles. Since AAC blocks are made from fly ash – an industrial waste product – generated by thermal power plants, it offers a low cost and sustainable solution for today and tomorrow. AAC is a requisite for green buildings.
It is easy to transport AAC blocks as it does not suffer from high transit breakage usually associated with clay bricks.
AAC blocks do not lose strength or deteriorate over time. Buildings constructed with AAC blocks do not require routine repairs that are required for buildings using clay bricks.
AAC blocks and panels offer excellent thermal insulation. This reduces recurring cost of energy required for heating and cooling. Better thermal insulation also allows usage of smaller HVAC than required conventionally.
Shorter Project Duration
Buildings can be built with AAC blocks 50% faster compared to clay bricks. This translates to lower project completion times benefiting project developers.
Due to high fire resistance offered by AAC blocks, structures made from AAC blocks have higher rate of survivability in case of fire.
Sound absorption properties of AAC make it ideal material for reducing ambient noise. AAC is well-suited for establishments like hospitals and offices situated in noisy areas.
Millions of air pockets in AAC cushion structure from major force and prevents progressive collapse of a building. AAC structures are known to maintain structural integrity despite of seismic activity (earthquakes), heavy rains, extremely low temperature and salty air.
Contribution to Nation
AAC factories create many jobs directly and indirectly creating a social impact. Along with that they pay Excise Duty and VAT contributing to national economy.
