5 Before the brick is fired, it must be dried to remove excess moisture. If this moisture is not removed, the water will burn off too quickly during firing, causing cracking. Two types of dryers are used. Tunnel dryers use cars to move the brick through humiditycontrolled zones that prevent cracking.
Fly ash clay bricks are manufactured with clay and fly ash—a byproduct of coal burning—fired at about 1,000 degrees C. Because fly ash contains a high volume of calcium oxide, this type of brick is sometimes described as selfcementing, since it expands when exposed to moisture.
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.
