摘　　要：工业建筑及海滨建筑混凝土结构耐久性问题非常突出,大量在役混凝土结构由于氯盐侵蚀钢筋锈蚀、混凝土劣化严重,使用寿命远小于设计使用年限。为了研究在不同浓度氯盐侵入混凝土所采用的修复技术和修复工艺,对掺入3%、6%、9%和12%四种浓度的严重锈损混凝土试件采用4种修复方案进行对比试验研究,并对其修复效果进行评估,给出掺入不同浓度氯盐情况下的阻锈修复方法和建议。The durability of industrial building and coastal concrete structure is also very prominent.Due to steel corrosion caused by chloride salt,and concrete degradation,there are lots of in service concrete structures are facing the problem that the structural life is less than the design life.In order to study the remediation techniques and repairing techniques used to penetrate concrete in different concentrations,of chlorinated salt,four kinds of repair schemes were used to compare the serious corroded reinforced concrete specimens with concentration of 3%,6%, 9%and 12%and assess the repair effect.The rust repairing method and suggestion were given in the case of different concentration of chlorine salt in concrete.
