摘　　要：采用电化学方法对含高氯盐混凝土进行除氯盐试验,在得出除盐效率与除盐后微观结构变化规律的同时,对混凝土中的钢筋进行中心拉拔试验,得出除盐后钢筋与混凝土黏结力变化规律,并对变化原因进行分析,探讨应对不良变化的措施。The extraction of high amount of chloride contained in concrete through Electrochemical Chloride Extraction（ECE） experiments.These experiments help to find out the rate of chloride extraction and some regular patterns about the changes of microstructure in steel reinforced concrete.Besides,pull-off tests are given to the center of steel bars in concrete in order to find out the pattern of change in adhesion strength between steel bars and concrete.This paper aims also to discuss the causes of these changes and the possible solutions to the adverse changes.

关 键 词：电化学除盐 拉拔试验 黏结力损失
