Parameters determining the quality of corrosion damage, induced by impressed current density technique, on steel reinforcement

Abstract

PurposeIn the present study, an effort has been made to estimate the effect of significant parameters on the vulnerability of steel reinforcement to corrosion, using both impressed current density technique and Tafel extrapolation method.Design/methodology/approachFive sets of tests were performed. Corrosion vulnerability of various diameters, temperature and pH effect on the corrosion process, potential corrosion tendency after a precorrosion period and declination from the theoretical damage prediction model are some of the parameters examinedFindingsThe results of the tests provide useful information on the main parameters, determining the quality of the corrosion damage.Originality/valueThe originality of the present study is the fact that an effort has been made to estimate the effect of significant parameters on the vulnerability of steel reinforcement to corrosion, using both impressed current density technique and Tafel extrapolation method. Interesting conclusions emerged.
