Abstract: The classification and the preparation process of ceramsite, the principle of preparing it from industrial solid waste, the technology of preparing ceramsite from fly ash, tailings, waste residue and sludge, and the application of ceramsite as adsorption material, concrete block and proppant were summarized. It is pointed out that the technology of preparing ceramsite from solid waste have research foundation and high feasibility, which is an important way to develop solid waste resource utilization. It is considered that the resource characteristics and cost advantages of bulk solid waste should be fully utilized in the future to prepare lightweight, porous and high-strength ceramsite, and improve the comprehensive performance of products, and the key to the large-scale application of ceramsite preparation by sintering method is to reduce production energy consumption through formula optimization and equipment development.
Keywords: industrial solid waste; ceramsite; fly ash; tailings; waste residue; sludge
