Electrochemical extraction of chlorides from reinforced concrete using a conductive cement paste as the anode

The results of this research show the viability of using a conductive cement paste anode for the electrochemical extraction of chlorides from reinforced concrete with an efficiency similar to that obtained with a classic Ti–RuO2 anode. The obtained efficiencies are within the typical range of values of overall efficiencies found for such treatments.The thickness of the conductive cement paste anode has a great influence on the capacity of the anode to retain an important part of the extracted chlorides after finishing the electrochemical treatments.
