Foam concrete wiki
Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit like blocks. Composed of quartz sand (SiO2 with impurities), calcined calcium sulfate (CaSO4, a.k.a. plaster of paris), lime (CaO), cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave. Invented in the m… WebApplications of Foam Concrete. Due to low density, it is used as filling material for cavities in slabs, concrete pits, etc.. Light weight foundation can be constructed. Wall panels, floor, roofs can be constructed for thermal insulation. Production of light weight blocks and precast panels. Trench reinstatement.
