摘　　要：混凝土结构表面鼓包问题是属于不影响结构安全性的一般质量问题,但若不处理,将影响其耐久性。本文以长沙某高层剪力墙结构住宅工程为例,通过现场取样分析鼓包处混凝土内部化学成分及含量,对混凝土结构表面鼓包原因进行分析,提出有针对性的处理方案。应用结果表明:聚合物改性水泥砂浆喷涂修缮技术,对混凝土结构表面起到隔离、约束作用,且满足耐久性要求。本文结果可为高层或者超高层混凝土结构表面出现大面积鼓包问题进行高效修复处理提供参考。The problem of bulging on the surface of concrete structure is a general quality problem that does not affect the safety of the structure,and if it is not treated,its durability will be affected.A high-rise shear wall structure residential project in Changsha is taken as an example,the internal chemical composition and content of the concrete at the bulging place are analyzed by on-site sampling,the causes of the bulging on the surface of the concrete structure are analyzed,and a targeted treatment plan is proposed.The application results show that the polymer-modified cement mortar spraying and repair technology can isolate and constrain the surface of the concrete structure,and meet the durability requirements.The results can provide a certain reference for efficient repair of large-area bulging problems on the surface of high-rise or super high-rise concrete structures.
