摘　　要：通过实验对比研究了内掺型水泥基渗透结晶型防水材料(CCCW)对混凝土自愈合能力、力学性能和耐久性的影响,结果表明,CCCW内部的活性物质与混凝土中的化学物质发生反应生成不溶于水的白色结晶,填充混凝土的内部缺陷,可明显提高混凝土的自愈合能力和防渗水效果,同时对混凝土的力学性能和耐久性起到积极作用。The influence of cementitious capillary crystalline waterproofing material(CCCW)on the self-healing ability,mechanical properties and durability of concrete is studied through experimental comparison.The results show that the active substances inside CCCW reacted with the chemical substances in concrete to form insoluble white crystals,filling the internal defects of concrete.This can significantly improve the self-healing ability and waterproofing effect of concrete,and play a positive role in the mechanical properties and durability of concrete.
