Autoclaved Aerated Concrete consists of the unique combination of Tobermorite 11A molecules and air pores. Tobermorite 11A is a molecule that, once created, cannot physically decompose through heat, rot, corrosion or other chemical process and thus is very durable.

AAC products are produced using a mix of generally abundant-available raw materials like sand, cement, lime and gypsum. The raw materials are mixed with water, a very small amount of aluminum powder is added, and poured in large moulds.
