Abstract: “During the last decades, many durability problems have been recorded on reinforced concrete (RC) structures, which are located in coastal areas. Chloride corrosion is among the various degradation mechanisms of steel reinforcement which lead to the premature deterioration of RC structures. In this paper, an effort was carried out to increase the corrosion resistance of high ductility dual-phase steel (B500c), without any interference in the chemical composition or in the production mode, but through shot peening process. More specifically, shot peening treatment was used on the one hand in order to clean the surfaces of the steel bars and to remove the “impurities” that act as underlying destructive cores on them, and on the other hand, in order to create surface compressive stresses. The whole process was carried out according to the pertinent protocols, with the use of olivine pellets. Subsequently, the corrosion resistance behavior of the steel was experimentally examined, both with”
