Fly ash brick (FAB) is a building material, specifically masonry units, containing class C ily ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 oC 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. Sangopang bricks are eco friendly, not creating any environmental hazards. lt has long term strength, high workability, and better durability. It has high uniformity in shape and size could be supplied in every season.
