Autoclaved Aerated Concrete (AAC)

Autoclaved Aerated Concrete (AAC) cansists 80% air by volume, making lightest available walling material (weights 1/3d that of clay bricks).
Formed as a result of reaction of Aluminum on a proportionate blend of lime, Cement & flyash, the hydrogen gas that escapes creatos millions of tiny air cell's giving it a strong honeycomb like structure.

• Aluminum
• Gypsum
• Lime 20%
• Cement 20%
• Flyash 60%

It is further strengthened by high pressure steam Curing in Autoclaves.
Invented in 1923, AAC now accounts for 40 % of all construction in, UK 60 % of all construction in Germany. The rising in demand in India has been so phenomenal that in last 3 years the production has increased by almost 500 %
