Abstract: In modern industry, large numbers of solid wastes not only pollute environment but also occupy a great quantity of land. In order to change the waste material into things of value and utilize resources in a reasonable way, experiments were done to prepare a new environment-friendly building insulation material with fly ash, waste glass and clay as raw materials, and sugar mud as foaming agent, through smashing, ball milling, drying, molding and sintering. The results show that the building insulation material whose volume density, flexural strength and porosity are 1.265 g/cm3, 14MPa and 35% , respectively, is prepared with the mixture of 25wt% fly ash, 28wt% sugar mud, 14wt% waste glass and 33wt% clay under the forming pressure of 20MPa and sintered at 1060℃ for 30 min.
