摘　　要：对于海工混凝土结构或者是处于氯离子侵蚀条件下的混凝土结构,如果出现裂缝,则裂缝将成为侵蚀性离子进入混凝土的便捷通道,极易造成钢筋的锈蚀和混凝土破坏。试验选择在混凝土试件出现0.2 mm宽的裂缝后,对其进行硅烷溶液、乳液或者凝胶浸渍处理,然后再进行氯离子侵蚀试验。通过对试件氯离子二维含量的分析,验证了对带裂缝混凝土进行硅烷浸渍防护处理具有非常好的效果。If a crack appears in marine or concrete structures due to chloride corrosion, it will be a convenient channel for the chloride to penetrate into the concrete and easily corrode the steel bars and damage the concrete. A concrete specimen with a 0. 2mm-wide crack was prepared. After the specimen was soaked in a silane solution, emulsion and gel, a chloride ion corrosion test was carried out. The analysis of two-dimensional chloride content shows that the silane soakage treatment of cracked concrete seals the crack and prevents further corrosion.
