本文通过分析利用不同比例钢渣粗骨料等体积取代石灰石,对混凝土工作性、力学性能及耐久性能的影响。结果表明:混凝土坍落度经时损失随钢渣取代比例增加有所降低;各龄期强度在钢渣取代比例为60%时,达到最大值;利用钢渣等体积取代石灰石配制的混凝土抗冻融性、抗渗性及抗收缩性等耐久性均有所改善。微观结构表明钢渣粗骨料混凝土界面过渡区结构相对更为致密。 In this paper, through the analysis of different proportions of steel slag coarse aggregate replacement volume limestone, the concrete workability, mechanical properties and durability. The results show that the slump loss of concrete decreases with the increase of steel slag replacement ratio; the strength reaches the maximum when the slag replacement ratio is 60% at all ages; the concrete prepared by equal volume of steel slag replaces the limestone, Impermeability and anti-shrinkage and other durability have been improved. The microstructure shows that the structure of transition zone at the interface of steel slag coarse aggregate concrete is relatively more dense.
