Application and advantages of clay bricks

Clay brick is one of the main products of si-al series, which is made of clay clinker as aggregate and refractory clay as binder with Al2O3 content of 30-48%.Mainly used for heat boiler, glass kiln, cement kiln, chemical fertilizer gasifier, blast furnace, hot blast furnace, coking furnace, electric furnace, casting and casting steel brick.General clay refractory products

The burning process of clay brick is mainly the process of kaolinite continuous water loss decomposition to produce mullite (3Al2O3·2SiO2) crystal.SiO2 and Al2O3 in clay bricks form eutectic silicate with low melting point with impurities in the firing process, surrounding mullite crystal.

Clay brick local materials, cheap, durable, fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, widely used in civil construction projects.Waste broken bricks can also be used as aggregate for concrete.In order to improve the shortcomings of ordinary clay brick, such as small, self-weight and large consumption of earth, it is developing towards the direction of light weight, high strength, hollow and large.
