The invention discloses a method for producing high-salinity maritime work cement through mineral waste residue waste materials. The high-salinity maritime work cement is prepared from, by weight, 30-40 parts of mineral waste residues, 40-50 parts of sulphate aluminum cement clinker, 0.03-0.05 part of composite activating agents, 2-4 parts of early strength agents, 0.3-0.5 part of water reducing agents, 0.005-0.007 part of air entraining agents and 0.3-0.5 part of retarder. The method for producing the high-salinity maritime work cement comprises the steps that the mineral waste residue waste materials, the sulphate aluminum clinker, the composite activating agents and the early strength agents are smashed, ground into powder and homogenized respectively and then dosed, mixed and homogenized according to proportions, then the water reducing agents, the air entraining agents and the retarder are added, mixed and homogenized, and the product is obtained. The high-salinity maritime work cement has the performance of common cement, further has the excellent characters of early-stage hardness resisting, long-term corrosion resistance, retardation progressive increasing and the like, and is especially suitable for ports, wharfs and other engineering which are corroded by corrosive media.
