摘要
针对目前普遍存在的氯盐环境下因钢筋锈蚀导致混凝土结构过早劣化破坏现状,提出在外加电场作用下迫使混凝土中氯离子排出、钢筋重新钝化的电化学除氯修复新技术。介绍了混凝土结构电化学除氯技术的基本原理,分析了国内外在此方面的研究进展和存在问题,并提出了进一步研究的方向。
The premature deterioration of concrete structure due to steel corrosion has become presently prevalent in the chloride environments. Electrochemical chloride extraction is presented as a novel rehabilitation technology on the chloride contaminated structures. In this process, chloride ions are repulsed away from the coating concrete and the repassivation of the steel is induced by the application of an external electric field. The basic mechanism of electricalchemical chloride extraction is introduced, the progress and deficiency in previous studies on this subject are analyzed and the necessary research in the future is proposed.
