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:① solid 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.
