摘要
电化学除氯是一种新型混凝土无损修复技术,可以在不破坏混凝土结构的情况下排除钢筋混凝土结构中的氯离子并使钢筋恢复钝化。在国内外已有研究的基础上,阐述了电化学除氯的原理,分析了各因素对电化学除氯效果的影响,总结了电化学除氯后钢筋混凝土结构宏观性能与微观结构的变化,针对目前研究中的存在的问题提出未来研究的方向。
Electrochemical chloride extraction is a new type of concrete non-destructive repair technology,which can eliminate the chloride ion in reinforced concrete structure and restore the passivation of steel without destroying the concrete structure.Based on the existing researches both at home and abroad,the principle of electrochemical dechlorination was expounded,the influence of various factors on electrochemical dechlorination was analyzed,the macro performance and microstructure of reinforced concrete structure after electrochemical dechlorination were summarized.In view of the existing problems in the research,the future research direction is proposed.
