Overview

Fly ash brick (FAB) is a building material, specifically masonry units, containing class C 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 freeze-thaw cycles. Owing to the high concentration of calcium oxide in class C fly ash, the brick is described as "self-cementing". The manufacturing method saves energy, reduces mercury pollution, and costs 20% less than traditional clay brick manufacturing.

Advantages

  • High Fire Insulation
  • Due to high strength, practically no breakage during transport and use.
  • Due to uniform size of bricks mortar required for joints and plaster reduces almost by 50%.
  • Due to lower water penetration seepage of water through bricks is considerably reduced.
  • Gypsum plaster can be directly applied on these bricks without a backing coat of lime plaster.
  • These bricks do not require soaking in water for 24 hours. Sprinkling of water before use is enough.
