摘　　要：选用不同胶凝材料组合及其不同细度下的组分配伍对设计混凝土胶凝体系,采用干缩试验、平板试验和ASTM C1581圆环试验对不同胶凝体系的混凝土变形参数进行分析,得到了不同胶凝材料的组合、细度配伍对与混凝土抗裂性能的相互关系。The influence of the combination and fineness coordination of different cementitious materials on crack resistance of concrete were studied.With method of concrete drying shrinkage test,mortar fiat test and steel ring test（ASTM C1581 ） ,the effects of cement with different fineness, different kind of mineral admixture and their combination with each different fineness levels on the concrete deformation were discussed. And the relations between the various influencing factor and concrete cracking were carried out.
