Shaping or Molding of brick units. Fly Ash Bricks are manufactured through mixture of fly ash, cement and related raw materials which have dense composition. Compressed at 28 MPa and cured for 24 hours in a 66 °C steam bath, then toughened with an air entrainment agent, the bricks can last for more than 100 freeze-thaw cycles. This process involves homogeneous mixing of raw materials (generally fly ash, sand and lime), moulding of bricks and then curing of the green bricks. %���� Tütünlü, F., and Atalay,Ü., Utilization of fly ash in manufacturing of building bricks, 2 2-24 October 2001, International Ash Utilization S ymposium , Center for Applied Energy Characteristics of Fly Ash Bricks The standard size of the brick is 230mmx110mmx70mm.
