In AAC blocks prime ingredients are fly ash, cement, water, quicklime, aluminum powder, and gypsum. The cement strength provides hardness to block and instant curing mechanism by autoclaving. Gypsum provides long term strength to the block.
AAC blocks, fly ash bricks, solid concrete blocks, and CLC blocks are relatively new building materials which are now used as an alternative to red bricks. While comparing red bricks vs AAC blocks vs fly ash bricks vs solid concrete blocks vs CLC blocks, there arises confusion in selection of masonry units for constructing a house.

Similar to fly ash slurry, the sand slurry is mixed in lime powder, gypsum, cement and aluminum powder. The AAC Blocks manufacturing process begins with the feeding of fly ash into slurry tank. A man feeds the ash inside the slurry tank to which powder, gypsum, cement and aluminum powder are added.
Fly ash in concrete is widely used across the to the strength of concrete. Fly ash suppliers such as CEMEX use it to improve workability of fresh concrete and reduce water demand, shrinkage and permeability of the finished product.
The strength test results on soil blocks stabilized with cement and fly ash are as shown in Curve 1 and 3 shows 5% and 25% of fly ash respectively and the strength increases mildly up to 3% of cement and then increases gradually. Curve 2 shows that due to increase of cement with 15% of fly ash
Fly ash brick (FAB) is a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 °C steam bath, then toughened with an air entrainment agent, the bricks last for more than 100 freezethaw cycles. Owing to the high concentration of calcium oxide in class C fly ash, the brick is described as ...
Feb 01, 2003· It can be observed from Fig. 1 that the strength of the hollow blocks increased with fly ash content initially, reaching a maximum value at fly ash content of 40%; beyond 40% the strength decreases. By reducing phosphogypsum content of FaL G hollow blocks from 30% to 20%, the strength of these blocks reduces for the same fly ash content.
