Development of method for assessing efficiency of organic corrosion inhibitors in concrete reinforcement

Ivana Šoić, Sanja Martinez, Ivana Lipošćak, Boris Mikšić

Abstract

The applicability of electrochemical impedance spectroscopy in a cell consisting of a steel plate covered with concrete layer containing chlorides and inhibitor, constructed in accordance with HRN EN ISO 16773, is studied for the first time in this paper. The measurements have enabled quantification of harmful chloride action and inhibitor efficiency, understanding the mechanism and time dependence of inhibitory activity, and visual inspection of metal surface after measurement. The results are consistent with the presumed physical model and point to the applicability of the method.
