Aerated autoclaved concrete is manufactured by mixing a silica rich material such as fine ground sand or fly ash, cement, a sulfate source such as gypsum, quicklime, a rising agent and water.In a first chemical reaction ;
The quicklime reacts with the water to form heat and calcium hydroxide. The calcium hydroxide, in turn, reacts with the water and rising agent to form hydrogen gas which expands the concrete mix to about twice its original volume, or more. Similar to bread rising, the mix expands into a porous mass. After expansion has occurred, the porous mass is cut to a desired size and shape
Second reaction ;
In autoclave to build strength, rigidity and durability with the cement component serving to harden the mass.
