Abstract: Corrosion rate of reinforcement is the best parameter to quantify the effect of corrosion of reinforcements. It gives the loss of steel and allows the estimation of the penetration of attack. However, most of the information found in the literature on this parameter concern short term tests in laboratory, lasting no longer than 1 or 2 years, or after isolated measurements in real structures.The present paper reports Icorr data measured during 10 years from reinforcements embedded in concrete specimens and submerged in natural sea water. The use of different binders and concrete covers for the reinforcements is taken into account through periodic measurement of the Icorr and Ecorr. Results indicate that the use of blended materials such as slag and fly ahs delay the despassivation time and contributes to increase the service life.
