摘　　要：在采用矿渣粉和粉煤灰复掺的基础上,以钢渣粉等比例取代矿渣粉,研究钢渣粉对混凝土工作性能、抗压强度、劈裂抗拉强度、微观结构和水化产物的影响。结果表明,钢渣粉与矿渣粉复掺有利于提高混凝土的流动性、抗压强度和劈裂抗拉强度,掺钢渣粉混凝土微观结构致密,钢渣粉水化速度介于矿渣粉和粉煤灰之间。Based on the double mixing of the fly ash and slag powders, the influence of steel slag powder on the working performance, compressive strength, splitting tensile strength, microstructure and hydration products of concrete are studied by replacing slag powders with an equal proportion of steel slag powder. The results show that the double mixing of the fly ash and slag powders can improve the liquidity, compressive strength and splitting tensile strength of concrete. The microstructure of concrete with steel slag powder is compact. The hydration speed of steel slag powder is between that of slag powder and fly ash.
