摘   要：研究了水泥基材料裂缝经防水卷材，防水涂料，水泥基渗透结晶处理后的短期、长期防水效果，并对其在冻融循环及干湿交替下的防水耐久性进行了分析比较。试验结果表明，防水卷材适用于迎水面处理裂缝，在冻融循环和干湿循环中容易出现部分或全部脱粘的现象，从而导致防水失效，防水卷材修复裂缝的防水耐久性主要取决于粘结层的耐久性；防水涂料适用于迎水面与背水面的裂缝处理，并且与水泥基材料结合良好，不容易脱落，在冻融循环和干湿循环中也体现出较好的防水耐久性，即使在循环次数增加时，失效也是一个渐变的过程；水泥基渗透结晶型修复材料适用于迎水面与背水面的裂缝处理，经养护后能够很好的起到防水作用，在冻融循环和干湿循环中，体现出了非常好的防水耐久性，其防水能力并未随着循环次数的增加而下降，体现出了永久防水和动态防水的效果。

Abstract: Short and long waterproof effects of cementitious material cracks after dealing with waterproof coiled materials, waterproof coatings and cement-based capillary crystalline are studied, and the waterproof durability under freeze-thaw cycles and alternation of drying and wetting is analyzed and compared. The results show that waterproof coiled materials are suitable for dealing with cracks in water surface , and in freeze-thaw cycles and circulation of wetting and drying, they can easily have part or total debonding phenomena, which make the waterproof failure. Waterproof durability of repairing cracks of waterproof coiled materials depends on the durability of bonding layer. Waterproof coatings are suitable for dealing with cracks in water surface, which combine with cementitious materials well and not break off. Waterproof durability has also good performance in freeze-thaw cycles and circulation of wetting and drying. Even the circles increase, the waterproof failure is a gradual process. Repairing materials of cement-based capillary crystalline are suitable for dealing with cracks in water surface. Through curing process, they can play a good role in waterproof. Under freeze-thaw cycles and circulation of wetting and drying, the repairing materials of cement-based capillary crystalline have very good waterproof durability. While the circles increase, the waterproof capacity has not decreased, and the repairing materials have the performances of permanent waterproof and dynamic waterproof.
