Ceramiste, a lightweight aggregate(LWA), has large numbers advantages: high strength, thermal insulation, anti-seismic and so on. The earliest ceramiste development happened in America, and then widely used in the developed countries, all that most used for buildings and bridges. However the ceramsite research was soon after the foundation of the PRC, and quickly developed around the end of the 1970s. Now ceramsite with high strength and high performance has produced all over word. Personally investigating, with the situation of the detailed technological process of clay-ceramisite and pictures, and there are some most important notices among the production. With great performance, ceramiste is widely used in some catagories, such as insulation concrete, great fillers for filtration ponds and planting.
