摘要
A ceramsite produced by using a river/lake/sea sludge and seashell powder as raw materials and a preparation method thereof are provided. The ceramsite is made of the following raw materials in parts by weight: 15-50 parts of shell powder, 5-15 parts of kaolin, 1-5 parts of peat ash, 15-30 parts of siliceous shale, 15-40 parts of furnace slag, 10-20 parts of fly ash, 15-40 parts of zeolite, 10-30 parts of river/lake/sea sludge, and 10-25 parts of peat. The shell powder is pulverized to a particle size of 60-200 mesh in fineness. A content of silica in the siliceous shale is 87.0%-89.5%. The preparation method of the ceramsite includes the following steps: taking raw materials, pulverizing, stirring, granulating, calcining, and naturally cooling, so as to obtain the ceramsite.
