摘　　要：论述了人工砂不同石粉含量对水工混凝土性能的影响。当石粉含量为最佳石粉含量时,混凝土的综合性能最优。人工砂最佳石粉含量随骨料岩性不同而有所不同。对于同种岩性的人工砂,混凝土单位体积的胶凝材料越富余,要求所使用的人工砂最佳石粉含量越低。This paper has a discussession on the effects that a mount of stone powder crushed sand on the properties of hydaulic concrete. When stone powder content in crushed sand is the best, the concrete can attain optimal combined properties. The best powder content of crushed sand varys with different lithology of the sand. As regard to the homogeneous lithological crushed sand, the more cementitious material contained in the concrete unit volume, the lower stone powder content in crushed sand is required.
