Aircrete Blocks

Aircrete blocks are made of a very fine-grained mixture of cement, quicklime, pulverised fly ash (PFA), sand, and water along with finely powdered aluminium. This mix results in hydrogen gas which results in the concrete mix’s aeration. Aircrete blocks are then loaded into autoclaves for steam curing. Aircrete blocks are used in loadbearing and non-loadbearing wall applications, mainly in the housing sector. Aircrete blocks in this assessment are assumed to be 100mm deep, 440mm wide, and 215mm high.Typical Compressive strength ranges between 2.9 to 10.4N/mm². Aircrete blocks thermal conductivity range between 0.09 to 0.21 W/mK.
