    Abstract

    The main goal of this study was to evaluate different corrosion measurement techniques in order to determine the most accurate methods for measuring the corrosion rate of steel bars in reinforced steel concrete. For this purpose, reinforced concrete specimens were cast and exposed to salt solution and the corrosion activity of the bars was investigated by half-cell potential, potentiostatic linear polarization resistance, galvanostatic pulse polarization, Electrochemical Impedance Spectroscopy, potentiodynamic cyclic polarization, and galvanodynamic polarization. The results obtained by the aforementioned methods were then compared with the actual mass loss of the steel bars due to corrosion (gravimetry test) and it shows that techniques based on applying potential are more reliable measuring techniques compared to those based on applying current.
