Autoclaved Aerated Concrete (AAC)

Sanlight AAC Blocks are manufactured from natural raw materials. The finished product is twice the volume of the raw material used, making it extremely resource-efficient and environmentally friendly.

What is AAC? And how it is made?

AAC is also known as Autoclaved Aerated Concrete it is lightweight concrete and it has been widely using across the world. Autoclaved aerated concrete or AAC is made by mixing cement, lime, fly ash, gypsum, water & aluminium powder the final mixture is poured into a mould. The reaction between aluminium and lime causes micros pic hydrogen bubbles to form lower density concrete by expanding it. After evaporation of the hydrogen and initial setting, aerated concrete is cut into required sizes and cured by steam-curing in a pressurized chamber (an autoclave) or low pressurized steam chambers. The result is a non-toxic, high strength, lightweight, airtight material that can be used for all walling and other applications. AAC is a green building material that generates no pollutants or hazardous waste during the manufacturing process.
