Autoclaved aerated concrete - Wikipedia
Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. Composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave.Invented in the mid-1920s, AAC simultaneously provides structure, insulation, and fire- and ...
Autoclaved Aerated Concrete Production | Masa …
Aerated concrete is made of the raw materials: silica sand, lime, cement, gypsum (anhydrite), aluminium powder or paste and water. In the wet ball mill (01), raw sand is processed to sand slurry which is stored in sand slurry tanks. Together with the other raw materials, the sand slurry is then transported to the Masa dosing and mixing plant (02).
