摘　　要：探究不同电流密度下电化学除氯参数对钢筋混凝土影响。本文通过控制电化学参数,对比混凝土内氯离子浓度和钢筋与混凝土之间粘结力的变化,研究电化学除氯技术对混凝土结构的影响。除氯初期,随电流密度的增加,排氯量增加;电流密度为1A/m^2的混凝土粘着力损失影响最小。The effects of electrochemical dechlorination parameters on reinforced concrete at different current densities were investigated.In this paper,the influence of electrochemical dechlorination technology on the concrete structure was studied by controlling the electrochemical parameters,comparing the chloride ion concentration in concrete and the bond between steel bar and concrete.With the increase of current density,the amount of chlorine discharge increased at the initial stage of dechlorination,and the adhesive loss of concrete with current density of 1 A/m2 was the least affected
