Abstract: Corrosion of reinforcement is one of the leading causes of the deterioration in reinforced concrete structures. Reinforced concrete is recognized to be durable and capable of withstanding a variety of environment conditions. Nevertheless, premature failures of structures still do occur as a result of steel reinforcement corrosion. RC structures damaged by reinforcement corrosion can exhibit not only reduction of the bearing capacity but also an alteration of the collapse mechanism with a reduction in the structural ductility. All of these actions contribute to the loss of stiffness and ductility of the RC Structure and thus, reduce the ultimate strength of the structure. This review paper focuses on the various studies of effect of accelerated corrosion on steel bar and its influence on strength and durability of RC structure. Thereby a comprehensive review of studies on strength of corroded RC columns & beams, concrete cover depth effect on crack width and its effect on corrosion, is presented.
