Abstract: An interface joint material based on industrial solid waste includes raw materials in parts by weight: portland slag cement, 80˜130 parts; metakaolin, 80˜130 parts; the industrial solid waste, 80˜130 parts; sodium silicate, 25˜35 parts; alkali, 8˜12 parts; acrylate, 30˜36 parts; a trivinyl ether compound, 1˜3 parts; inorganic sulfite, 1˜3 parts; persulfate, 1˜3 parts; a water reducing agent, 3˜6 parts, and water, 60˜80 parts. The interface joint material is suitable for a concrete interface of different components, with good bonding, high strength, and the advantages of pumping, fast hard, early strength, micro expansion and high ductility; In addition, the industrial solid waste is added into the interface joint material, which improves a utilization rate of the industrial solid waste in construction joint materials, and has significant for recycling of the industrial solid waste.
