摘　　要：针对人工砂副产物石灰石粉部分取代水泥熟料，研究混凝土的立方体抗压强度和抗冻性能。试验结果表明，5％-10％的石灰石粉取代水泥熟料配制混凝土是完全可行的，且混凝土的强度比基准混凝土高，抗冻性能较好，但是石灰石粉取代量继续增加时，混凝土的强度和抗冻性能都有所降低。The limestone powder, byproduct of artificial sand partly replacing cement clinker as mineral admixture was made concrete, and concrete compressive strength and frost resistance were studied in this paper.The experimental results showed that, concrete with 5%-10% limestone powder was completely feasible, concrete cube compressive strength was higher than the reference concrete, frost resistance of concrete was better than base concrete, concrete compressive strength decreased and frost resistance degraded when limestone powder in-creased.
