Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material, eco-friendly, [1] suitable for producing concrete-like blocks. It is composed of quartz sand , calcined gypsum , lime , portland cement , water and aluminium powder .
Perlite mine in Owens Valley, California. Perlite is a non-renewable resource. The world reserves of perlite are estimated at 700 million tonnes. [4] The confirmed resources of perlite existing in Armenia amount to 150 million m 3, whereas the total amount of projected resources reaches up to 3 billion m 3. [5]
Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The heating process causes gases trapped in the clay to expand, forming thousands of small bubbles and giving the material a porous structure.
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, [17] [18 ...
It is created by using small lightweight EPS balls (sometimes called Styrofoam) as an aggregate instead of the crushed stone that is used in regular concrete. [3] It is not as strong as stone-based concrete mixes, but has other advantages such as increased thermal and sound insulation properties, easy shaping and ability to be formed by hand ...

Lightweight concrete is often achieved by adding air, foams, or lightweight aggregates, with the side effect that the strength is reduced. For most routine uses, 20 to 32 MPa (2,900 to 4,600 psi) concrete is often used. 40 MPa (5,800 psi) concrete is readily commercially available as a more durable, although more expensive, option.
