Effect of corrosion method of the reinforcing bar on bond characteristics in reinforced concrete specimens

The results of this investigation indicated that the failure pattern and the critical corrosion level at which the bond capacity failed, varied depending on the RC corrosion method. The RC specimens were deteriorated at a low corrosion stage under natural corrosion conditions. More attention is needed to be given to the rapid artificial RC member corrosion method. Non-destructive test (NDT) methods were also applied to RC specimens for investigation of the naturally corroded members. A formula of corrosion area prediction from NDT was proposed.
