The invention relates to slag Portland cement and a preparing method thereof and relates to the field of building materials. The slag Portland cement comprises following components by mass: (1) 30.0-65.0% of silicate Portland cement clinker, (2) 5.0-15.0% of copper slag, (3) 15.0-30.0% of blast furnace slag, (4) 5.0-15.0% of molybdenum slag, (5) 5.0-12.0% of flue dust and (6) 2.5-5.0% of gypsum. The slag Portland cement is high in hydraulicity performance, short in interval between initial setting time and final setting time, high in later strength, high in compression resistance and suitable for use in various occasions. The preparing method adopts a process including primary smashing, mixing and grinding. The prepared cement is low in particle size, uniform in quality, high in specific surface area, and improved in hydraulicity performance.
