    A carbon fiber reinforced polymer (CFRP) was adopted as an external anode in the electrochemical chloride extraction (ECE) treatment for reinforced concrete cylinders, which were cast with different water–cement ratios and amounts of chloride. Three constant current densities were applied during the electrochemical chloride extraction, with the internal steel bar as the cathode. The chloride extraction ratio (i.e. proportion of residual chloride) and the Cl-/OH- ratio were obtained to assess the efficiency of the electrochemical chloride extraction. The results confirmed the feasibility of the electrochemical chloride extraction with an external CFRP anode.
