摘　　要：本文介绍了混凝土抗裂防渗材料研究。试验结果表明该抗裂防渗混凝土的抗渗标号达S40 以上 ,混凝土早期开裂得以消除 ,具有良好的工作性能且经时坍落度损失小 ,3d平均强度大于 42MPa,2 8d大于6 0MPa。The crack-resistance and impermeability concrete is introduced in this paper. The experiment results reveal that the concrete impermeability grade is S 40 or more, and early-crack in concrete can be eliminated;It has excellent workability property and low lump-loss,and the compressive strength is more than 42MPa in 3d and 60MPa in 28d.
