The increasing application of electrochemical chloride extraction (ECE) in concrete has aroused great interest in the understanding of the mechanisms involved in this technique. There are many gaps remaining to be filled in relation to the processes taking place at the electrodes and how to detect the moment in which the rebar is re-passivated. The usual methods to control the efficiency of the treatment involve extraction and chemical analysis (chloride ions) of cores from the structure. The corrosion potential and corrosion rate measured by the Polarization Resistance technique are the suggested non-destructive indicators of the efficiency of the technique at the end of the treatment but it is not possible to use these parameters as passivity indicators during the treatment.The objective of this work is to determine by nondestructive electrochemical techniques the passivity state of the reinforcement and the mechanisms leading to this during the electrochemical chloride extraction treatment. In this way we can monitor the state of the rebar during treatment and confirm its effectiveness using only non destructive techniques based in electrochemical techniques such as electrochemical impedance espectroscopy (EIS)
