Stainless steel slag tailing mud and slag composite cement and preparation method thereof

The invention discloses stainless steel slag tailing mud and slag composite cement and a preparation method thereof, and belongs to the technical field of building materials, and the composite cementcomprises the following components in parts by weight: 40-95 parts of Portland cement clinker, 10-30 parts of stainless steel slag tailing mud, 10-30 parts of granulated blast furnace slag and 3-6 parts of gypsum. According to the invention, the stainless steel slag tailing mud and the granulated blast furnace slag are combined and complement each other's advantages and disadvantages, so that theprepared composite cement meets the requirements of various physical properties of cement, the compressive strength grade meets 42.5 MPa, and the heavy metal leaching value meets the standard requirements. Various waste residues can be comprehensively utilized, waste is turned into wealth, and economic value can be created. 本发明公开了一种不锈钢渣尾泥和矿渣的复合水泥及其制备方法，属于建筑材料技术领域，所述复合水泥各组成分占重量份数：硅酸盐水泥熟料40～95份，不锈钢渣尾泥10～30份，粒化高炉矿渣10～30份，石膏3～
