17-12-2018· Juan Rodriguez. Updated December 17, 2018. Autoclaved aerated concrete (AAC) is a type of precast concrete composed of natural raw materials. It was first developed in Sweden in the 1920s, when an architect first combined the conventional concrete mixture of cement, lime, water, and sand with a small amount of aluminum powder.
Autoclaved Aerated Concrete Market - Snapshot. Autoclaved aerated concrete (AAC), also known as autoclaved cellular concrete (ACC) or autoclaved lightweight concrete (ALC), is an eco-friendly green building material. The raw material used for the production of AAC is fly ash, which is a leftover product of thermal power plants.
01-06-2008· Autoclaved Aerated Concrete (AAC) is a lightweight, concrete-like material with many small, closed internal voids. Material specifications for AAC are prescribed in ASTM C1386. AAC typically weighs one-sixth to one-third as much as conventional concrete, and is …
In general, autoclaved aerated concrete (AAC) is an ultra lightweight concrete with a distinct cellular structure. It is approximately one-fifth the weight of normal concrete with a dry bulk density ranging from 400-800 kg/m 3 (25-50 pcf) and a compressive strength ranging from 2 to 7 MPa (300-1000 psi) ( …
There are two types of aerated concrete: non-autoclave and autoclave hardening. Advantages and disadvantages of aerated concrete are discussed below. Thanks to presence lime, the quantity of cement used is lower, so, the cost of raw materials for manufacturing autoclave aerated concrete is lower than that of the non-autoclave one.
24-10-2020· Introducing Autoclaved Aerated Concrete (AAC) AAC is a form of pre-cast concrete comprised of natural raw materials. This concrete has been first developed in Sweden in the early 1920s. Everything started when an architect has mixed the conventional concrete combination of water, cement, lime, sand with a small amount of aluminum powder.
