摘　　要：以钢渣复合材料取代矿粉、砂、石用作混凝土掺和料与骨料为核心展开试验。试验方法为:准备3组配合比不同的混凝土材料,A组钢渣粉与矿粉的配合比为1∶1,B组为2∶3,C组为3∶7,然后进行混凝土制备,研究混凝土试件的收缩性和抗压性能,分析钢渣粉代替矿粉、砂、石对混凝土性能的影响。结果表明,钢渣复合材料用作混凝土掺和料与骨料时,只要配比适宜便可有效强化混凝土强度。The test was carried out with steel slag composite material replacing mineral powder,sand and stone as the core of concrete admixture and aggregate.The test method is as follows:prepare 3 groups of concrete materials with different mix ratios,the mix ratio of steel slag powder and mineral powder in group A is 1:1,group B is 2:3,and group C is 3:7,and then prepare concrete,study the shrinkage and compressive properties of concrete sample,and analyze the influence of steel slag powder replacing mineral powder,sand and stone on the performance of concrete.The results show that the steel slag composite material can effectively strengthen the strength of concrete as long as the ratio is suitable when used as concrete admixture and aggregate.
