Celcrete Autoclaved Aerated Concrete (AAC) is a solid, inert, genuine masonry building material that has been used in Europe for over 80 years. It is available in block or cladding systems.

Autoclaved Aerated Concrete (AAC) was developed by the Swedish architect, Johan Eriksson and was patented in 1924. He succeeded in producing a highly cellular, lightweight material from a mixture of quartzite, sand, lime and water.

The high-pressure steam curing in autoclaves achieves a physically and chemically stable product with the average weight being approximately one fifth that of standard concrete. AAC comprises myriads of non-connecting air cells, which together with the solid structure of calcium silicate hydrates give the material its incredibly diverse qualities.
