摘　　要：为了研究矿渣胶凝材料配比对水泥砂浆抗裂性能的影响,对不同掺量下矿渣胶凝材料的抗折强度和抗弯拉弹性模量进行了测试,并分析了矿渣胶凝材料弹性模量的影响机理。试验结果表明:矿渣胶凝材料具有弹性模量小,抗裂性能好等优点。其最佳掺量为矿渣72%～74%,石灰石4%。随着抗折强度的增加,矿渣胶凝材料弹性模量降低。To investigate the effect of mix proportion of slag cementitious materials on cement mortar cracking resistance, the flexural strength and elastic modulus were tested for different fractions, and the mechanism of elastic modulus of slag cementitious materials was analyzed. The experiment results show that the slag cementitious material is a good cementitious because it has short bending elastic modulus and good cracking resistance. The optimum slag ranges from 72% to 74%, and the optimum limestone is 4%. And elastic modulus decreases as the flexural strength increases.
