What are the characteristics of aerated concrete?

Aerated Concrete has the following properties:

• It can be sawn, cut, nailed. It can hold nails.
• It is quite durable.
• The rate of water penetration through aerated concrete is low.
• It has better resistance to frost.
• Its water absorption is high.

Is aerated concrete strong?

Aircrete is a material that combines strength, durability, and lightweight properties that make it easy to work with when building. It’s relatively inexpensive when compared to concrete and has a less environmental impact. Aircrete is not as strong as concrete. It is 50\% the strength of regular concrete.

What is aerated concrete used for?

Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit 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.

Is aerated concrete fireproof?

The gas used to ‘foam’ the concrete during manufacture is hydrogen formed from the reaction of aluminium paste with alkaline elements in the cement. AAC is durable and light, does not burn, is an excellent fire barrier and a good insulator, and is able to support quite large loads.

What is an aerated concrete wall?

Autoclaved aerated concrete (AAC) is made with fine aggregates, cement, and an expansion agent that causes the fresh mixture to rise like bread dough. In fact, this type of concrete contains 80 percent air. In the factory where it is made, the material is molded and cut into precisely dimensioned units.

What aerated concrete blocks?

Aerated concrete or ‘aircrete’ block The blocks are made from cement, lime, sand, pulverised fuel ash (PFA) and water. PFA is mixed with sand and water to form a slurry. This is then heated before being mixed with cement, lime and a small amount of aluminium sulphate powder.
