摘要：综述氯盐类融雪剂对混凝土的侵蚀破坏机制和混凝土抗氯离子侵蚀性能的提升方法。氯盐类融雪剂对混凝土的侵蚀破坏机制可以分为化学侵蚀与物理破坏,化学侵蚀主要包括碱(土)金属离子侵蚀和氯离子侵蚀,物理破坏主要包括结晶破坏和剥蚀破坏。氯盐类融雪剂对混凝土及生态环境均具有一定的危害性,但由于性价比极高,因此未来仍是除冰的主流选择。目前延缓混凝土受氯离子侵蚀的手段主要有提高致密性、超疏水改性以及优化胶凝材料,综合使用可达到最优的防护效果。解决氯离子侵蚀问题的关键是控制混凝土的低水灰比来抑制水分在混凝土中的传输,以提升混凝土的服役寿命。

Abstract：The erosion and damage mechanism of chloride salt snow melting agents on concrete and the method to improve the performance of concrete against chloride ion erosion were reviewed, which could be divided into chemical erosion and physical damage, the former mainly includes base ion erosion and chloride ion erosion, and the latter mainly includes crystallization damage and exfoliation damage. Chloride salt snow melting agents on the concrete and the ecological environment have a certain degree of harm, but due to its extremely cost-effective, the future remains the mainstream choice. At present, the main means of delaying concrete erosion by chloride ions are to improve the densification, modified ultra-hydrophobic and optimization of cementitious materials, a variety of means used can achieve the optimal protection effect. It is considered that the key to solve the chloride ion attack is to control the low water-cement ratio of concrete to inhibit the transport of water in concrete in order to enhance the service life of concrete.
Keywords：concrete; snow melting agent; chloride ion corrosion; durability
