摘　　要：为了拓宽与升级工业固体废弃物的综合利用途径,研究了加入煤矸石、磷石膏、赤泥等固体废弃物对煤矸石基胶凝材料力学性能的影响。研究结果表明:①掺入合理配合比的固体废弃物可制备力学性能优良的胶凝材料;②掺入适量的磷石膏对胶凝材料早期的力学性能有一定提升;③赤泥与矿渣的掺比合理有利于增强煤矸石基胶凝体系的强度。In order to broaden and upgrade the comprehensive utilization of industrial solid waste,the effects of adding solid wastes such as gangue,phosphogypsum,and red mud on the mechanical properties of gangue-based cementitious materials are studied.The research results show that:①solid waste with reasonable mixing ratio can be used to prepare cementitious materials with excellent mechanical properties;②by adding an appropriate amount of phosphogypsum,it can improve the early mechanical properties of cementitious materials;③a reasonable mixing ratio of red mud and slag is conducive to enhancing the strength of the gangue-based cementitious system.
