连云港市沿海水工建筑物混凝土结构易受氯离子侵蚀,钢筋锈蚀病害十分严重。用普通水泥砂浆局部修补处理病害屡遭失败。本工程采用阻锈型补偿收缩水泥砂浆全面更换钢筋的保护层,外加高压无气喷涂高效环氧厚浆涂料全封闭加强保护等两项新技术进行防护修复试点,取得了较好的技术经济效益。 Lianyungang coastal hydraulic structures are susceptible to chloride ion erosion of concrete structures, steel corrosion disease is very serious. Local cement mortar repair with local repair failures have failed. The project uses the compensation of shrinkage-compensated shrinkage cement mortar to replace the protective layer of steel reinforcement, plus high-pressure airless high-performance epoxy mortar paint fully enclosed to enhance protection of two new technologies for protection and repair pilot, and achieved good technical and economic benefits .
