砼建筑物由于受到腐蚀而出现的疏松,剥落等现象已屡见不鲜。由于腐蚀性介质的作用而引起结构材料破坏,这将会造成生产及生活方面的巨大经济损失,因此对砼建筑物的修补已日益引起人们的重视。 引起砼受腐蚀而破坏的主要原因是碳化过程和盐雾侵蚀。沿海城市及盐碱地区,砼受盐雾侵蚀的现象较为普遍。另外,冬天使用的去冰盐水,也会对道路、 疏 The phenomenon of looseness and flaking of buildings due to corrosion has become commonplace. The destruction of structural materials caused by the action of corrosive media will cause huge economic losses in production and life. Therefore, the repair of concrete buildings has attracted increasing attention. The main cause of the damage caused by corrosion of the crucible is the carbonization process and salt spray erosion. In coastal cities and saline-alkali areas, the phenomenon of salt spray is widespread. In addition, the ice-free salt water used in winter will also
