What is Autoclaved Aerated Concrete (AAC)?

AAC is a pre-cast, concrete building material made of cement-based, non-organic components that are available in large building blocks and reinforced or unreinforced panels, planks and special elements. It is a cellular, lightweight and structural material that has thermal and acoustic insulation as well as fire, mold and insect resistance. Almost every portion of the structural and insulation requirements of a building can be satisfied with AAC. AAC is claimed to be the only viable, single component and structural insulation system available. Building walls, floors and roofs can be constructed with AAC allowing excellent design flexibility, quick construction and reduced waste.

The History of AAC…

AAC was developed in Europe in 1923 with commercial production beginning in 1930. AAC products have been used for construction projects worldwide since the 1920s in different climatic conditions ranging from the severe cold in northern Japan and Europe, to the hot and humid regions of South America, and to the far east hot and dry climates of Australia and the Middle East.
