| Abstract: | Deterioration of bond strength due to reinforcement corrosion is one of the main causes for losses in mechanical performance of RC members. The effect of corrosion on bond between reinforcement and concrete has become the priority research area for the durability of RC structures. The paper presents test methods for bond behavior evaluation and corrosion tests. The effects of corrosion on bond and bond-slip behavior are systematically summarized. The influence of reduction of bond properties on the strength of RC structures is reviewed, too. |
