Lightweight aggregate is also called the ceramsite. which is a kind of ceramic quality of a material of artificial particles, high strength, fire prevention performance good weathering resistance and other functions. It is one of the most excellent of lightweight construction materials. It can resolve weight, fire prevention, heat insulation, thermal insulation, such as the engineering difficulties. The nature of ceramsite is resistance to weathering, superior quality and competitive price, environmental protection, easy to make. So it can be a host used in the precast wall panel (dry wall), interwall and lightweight concrete, the roof insulation, precast concrete, small lightweight block, ceramsite brick, etc., it can also be used for gardening, flowers, municipal, and soilless cultivation market, etc. The specifications ceramsite is 5-15 mm, the tube pressure strength is 1.5-4.5 MPa and the bulk density is 300-900 kg/m³.
