摘　　要：主要选取了钢渣、矿渣2种工业废弃物作为水泥掺合料,通过2种掺合料的活性匹配与颗粒级配调控制备出高活性的钢渣矿渣复合掺合料。将粗粒度钢渣(D_(50)>32μm)与细粒度矿渣(D_(50)<8μm)与商品硅酸盐水泥进行配伍,制备出的钢渣矿渣复合掺合料7 d抗压活性指数可达到94%,28 d抗压活性指数可达到101%。This paper examined steel slag and GBFS are mainly selected as cement admixtures,and high-activity composite admixtures are prepared through optimized matching and particle gradation control.The composite admixture of steel slag and GBFS prepared by combining coarse-grained steel slag with fine-grained GBFS and commercial Portland cement.It’s attainable that the compressive strength reactivity index of the composite admixture in the age of 7 d is 94%,and in the age of 28 d is 101%.
