Airolite AAC Blocks is a lightweight material produced by mixing silica rich material (sand or fly ash/pond ash), cement, lime, gypsum, aluminum powder/paste and water. Aluminium acts as a catalyst. It generates hydrogen gas upon reacting with cement and lime during AAC manufacturing process. Hydrogen gas escapes from concrete mix imparting a porous structure to AAC blocks and panels. Airolite AAC blocks are so lightweight, it weighs 1/5th of the weight of the standard concrete, which results in lower transportation costs, faster work-flow lower material handling costs etc. Airolite AAC Blocks is in 'ready to build' material, requiring no onsite curing time. It has unparalleled workability because it can be sown, drilled, nailed, screwed and milled with common hand tools. AAC products offer superior insulation, cost-effectiveness and durability compared to clay bricks.
