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3～6份。本申请将不锈钢渣尾泥和粒化高炉矿渣两种废渣进行结合，优劣互补，制备出的复合水泥满足符合水泥各项物理性能要求，抗压强度等级满足42.5MPa，重金属浸出值符合规范要求。既能将各类废弃废渣综合利用，实现变废为宝，又能创造经济价值。
