Description
Summary:A new method to quickly assess the efficiency of corrosion inhibitor was developed by electrically accelerating chloride ions diffusing onto the surface of the embedded steel bar in concrete and inducing corrosion. Potentiodynamic polarization scanning and linear polarization method were used to evaluate the corrosion states which were compared with the direct observation of the bar surface by breaking the sample. The test duration was about two days and the results clearly show the differences in efficiency of the inhibitors tested.
