Sialite, made according to the theory of simulation to formation of rock, is a new aluminosilicate-based cementitious material. Production of sialite does not require calcination, which consists of a main body (90%-97%) and an auxiliary body. Main body is made up of solid wastes such as fly ash, gangue, blast furnace slag, steel slag, red mud, waste bricks, waste glass and any other types of slag produced as a by-product in burning processes. The auxiliary body is a diagentic substance made by natural minerals. Sialite products have been successfully put into practice, which have the characteristics of cleaning production and low consumption of natural resources. Therefore sialite technology would provide an efficient method for promoting the development of a sustainable economy.
