摘　　要：为探究钢渣与水镁石纤维对混凝土性能的影响,使用钢渣砂替代普通砂,掺入水镁石纤维作为增强体制备混凝土,而后测试了混凝土的工作性、抗压强度与抗弯拉强度。结果表明:钢渣砂与水镁石纤维均会使混凝土坍落度降低;钢渣砂会降低混凝土的抗压强度与抗弯拉强度;水镁石纤维对混凝土有增韧作用,可弥补钢渣砂对混凝土强度的负面影响。In order to explore the influence of steel slag and brucite fiber on the properties of concrete,steel slag sand was used instead of sand,and brucite fiber was added as reinforcement system to prepare concrete,and then the working ability,compressive strength and flexural tensile strength of concrete were tested.The results show that both steel slag sand and brucite fiber can reduce the slump of concrete.Steel slag sand can reduce the compressive strength and flexural tensile strength of concrete.Brucite fiber can toughen concrete and compensate for the negative effect of steel slag sand on concrete strength.
