What Is AAC? (Light Weight Concrete)

Autoclaved Aerated Concrete (AAC) is manufactured from cement, sand (silica), lime and water, it is aerated by adding an expanding agent to the mix (small amounts of aluminum paste). The mix is poured into a mold (a very large cake tin), to approximately 2/3 of the height of the mold, almost instantly the expanding agent reacts with the other elements, and the mix begins to rise in the mold. (A chemical reaction expands the mixture to form small, finely dispersed air bubbles).

The molds are pre‐cured in a heated room for several hours. Then the semi ‐solid material (still in a green state) is transported to the cutting machine. The soft but semi-solid block is sliced into the required panel size using steel wires. Once sliced, the block is steam pressure cured in autoclaves for up to 12 hours. The expanding chemical reaction combined with the Autoclave process is what gives AAC it’s unique properties. AAC has excellent thermal insulation and acoustic absorption properties, it has superior fire resistance qualities and is also termite resistant.

Its properties and specification satisfy all relevant building codes. Working with AAC is easy and efficient. AAC is both versatile and economical. AAC meets the diverse demands better than any other material due to the numerous advantages of its physical and mechanical properties.
