摘要
结合工程实例,介绍了框架柱裂缝、钢筋锈蚀的现象和成因,简述了混凝土中氯离子含量偏高是钢筋锈蚀的主因,并提出了用置换混凝土加固法置换柱内全部含氯离子混凝土的加固方案和施工要点。具有一定的参考价值。
It was presented that the phenomenon and cause of crack rebar corrosion of frame columns according to case histories.It was also pointed out that a higher content of chloride ion in concrete was the main cause of rebar corrosion, it was finally proposed the scheme of replacing all the concrete containing chloride ion in the columns by replaced concrete strengthening, whose construction key points were given.
