Molybdenum tailings and fly ash pertain to bulk solid waste,which pose great harm to the ecological environment due to long-term and large-scale storage.Research has been conducted on the preparation of inorganic mineral polymer materials using molybdenum tailings and fly ash as raw materials,metakaolin as a regulator,and alkaline activation.The aim is to achieve high value-added utilization of these two solid wastes and reduce their damage and pollution to the ecological environment.The optimal ratio and preparation process of inorganic mineral polymers were determined through single factor experiments.The 7 d compressive strength,water absorption ratio,and density of the prepared inorganic mineral polymer material were 27.79 MPa,2.18%,and 2.34 g/cm3,respectively.The XRD pattern analysis results showed that a composite material with a certain proportion of inorganic mineral polymers was prepared,which has broad application prospects in non-fired bricks,artificial stone decorative materials,substrate repair materials,and other fields.
