In this study, influence of revibrating conditions on bond strength by changing diameter of steel bar were investigated. Parameters included diameter of steel bar, timing of revibration, duration of revibration and duration of contact between steel bar and internal vibrator. As a result, bond strength showed a decrease when diameter of steel bar is larger. And the influence of revibration and contact between steel bar and internal vibrator showed an increase when diameter of steel bar is smaller. This paper also proposed an appropriate method of revibration including difference diameter of steel bar.
