All About Autoclaved Aerated Concrete (AAC)

16/12/2018  Autoclaved aerated concrete (AAC) is a type of precast concrete composed of natural raw materials. It was first developed in Sweden in the 1920s, when an architect first combined the conventional concrete mixture of cement, lime, water, and sand with a small amount of aluminum powder. The aluminum powder serves as an expansion agent that

Reinforced Autoclaved Aerated Concrete (RAAC)

These panels consist of autoclaved aerated concrete (sometimes called Aerated concrete) reinforced to form structural precast units. This form of concrete (really an aerated silica product) provides little protection to the corrosion of embedded metal and therefore a bituminous or cement latex coating is applied to the reinforcement as protection. It is typically used for walls,
