Bond deterioration of corroded steel bars in concrete
Corrosion of embedded steel bars continues to be the principal cause of deterioration of reinforced concrete structures. The most obvious effect is the reduction in cross-sectional area of the affected steel bars. If corrosion is allowed to propagate over a sufficiently long period of time and proper interventions are not made, loss of the bond between the corroded steel bar and the surrounding contaminated concrete may also lead to impaired structural performance and safety of the affected structures. The present paper is devoted to a review of published pullout test data on bond strength of corroded steel bars in concrete. The experimental results are carefully evaluated in order to examine the influence on bond strength of parameters such as corrosion level, bar diameter, bar position, concrete cover, transverse reinforcement and impressed current density.
