EVALUATION OF ORGANIC CORROSION INHIBITOR EFFECTIVENESS INTO THE CONCRETE
Abstract The aim of this study is to examine the protective effect of N, N’ Dimethylaminoethanol (DMEA - organic corrosion inhibitor), against rebar corrosion in the presence of chloride ions. The inhibiting properties of DMEA based corrosion inhibitor were evaluated in saturated Ca(OH)2 solution and in cement mortar specimens. The electrochemical measurements were performed using saturated calcium hydroxide Ca(OH)2 solution, contaminated with chloride ions, simulating the concrete interstitial electrolyte. Corrosion parameters, such as corrosion rate, corrosion current density Icorr, polarization resistance Rp and pitting potential Epitt of reinforcing steel have been evaluated by electrochemical measurements and compared with that obtained from metal loss determination. Results indicated that the addition of N, N’ dimethylaminoethanol to the saturated Ca(OH)2 solution as well as into the concrete contaminated with chloride ions, decreases the corrosion rate of steel reinforcement.
