Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material. Developed initially in the mid-1920s, it has expanded into widespread use. Developed initially in the mid-1920s, it has expanded into widespread use.
Reinforced autoclaved aerated concrete (RAAC) is a lightweight form of concrete that was used in schools, colleges and other building construction from the 1950s until the mid-1990s, according to ...
Aerated concrete produced by the addition of an air-entraining agent to the concrete (or a lightweight aggregate such as expanded clay aggregate or cork granules and vermiculite) is sometimes called cellular concrete, lightweight aerated concrete, variable density concrete, Foam Concrete and lightweight or ultra-lightweight concrete, [18] [19 ...
