Abstract:Corrosion of steel reinforcement is the most important cause of premature failure in reinforced concrete structures. The use of corrosion inhibitors seems to offer a simple and cost effective prevention technique against chloride induced corrosion: nevertheless, performance of commercial inhibitors available on the market is only partially satisfactory. This paper deals with a basic study on organic substances, that present inhibiting effect on carbon steel corrosion. Two years electrochemical test results, obtained in simulated concrete pore solutions and concrete slabs, on the effect of functional groups are presented and discussed. The inhibition effect on corrosion initiationnd propagation was evaluated by means of two electrochemical parameters: potential and polarisation resistance. Tests on concrete specimens confirmed the effectiveness of some organic substances in delaying corrosion initiation and increasing the chlorides concentration threshold.
