AAC was invented in Sweden by an architect named Johan Axel Eriksson in early 1923. Although his purpose for inventing AAC was to overcome shortage of timber in Sweden, AAC has found global acceptance. AAC blocks and panels promise a welcome change to Indian construction industry as well.
Although AAC stands for Autoclaved Aerated Concrete, it has couple of other names too. Depending on geography it may be called Porenbeton, Gasbeton, Autoclaved Cellular Concrete (ACC), Autoclaved Lightweight Concrete (ALC) or just Aerated bricks.
AAC products offer superior insulation, cost-effectiveness and durability compared to clay bricks.
AAC is a lightweight material produced by mixing silica rich material , 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 blocks manufacturing process. Hydrogen gas escapes from concrete mix imparting a porous structure to AAC blocks and panels.
