摘要(Abstract)：

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。

关键词(KeyWords)： 混凝土;融雪剂;氯离子侵蚀;耐久性
