Autoclaved lightweight concrete (AAC) was invented and produced for the first time in the 1920s by Dr. Johan Alex Erickson, an assistant professor at the Stockholm Institute of Technology in Sweden. The motive behind its production was to protect forests and obtain materials with the properties of wood, such as lightness, thermal insulation, the ability to cut and shape, and on the other hand, without the disadvantages of wood, such as flammability, decay, destruction by termites, etc.

After that, in 1945, on the way to the development of this product, German innovators discovered how to cut it, and with the achievement of this technology, mass production began until it was approved and approved by the German standard (DIN) in 1958. since 1960 because of its affordability Construction with these materials, German scientists thought of strengthening it And in the process of this progress, in 1977, these materials in male and female form with precise cuts, problems Construction was kept to a minimum.
Since 1987, with the production of large pieces of this product, a revolution has occurred in the construction time, and the construction time has been greatly reduced, and since 1994, with new researches, the strength and lightness of this product has reached perfection.
