Abstract
A shear failure of RC beam with repaired honeycombing in the bottom of the beam was examined. The beam specimens were repaired by conventional or proposed method. In the loading tests, peeling at the repaired interface was observed in the conventional methods. Without anchorages, diagonal cracks easily occurred from the end of the interface and the shear strength was decreased. However, with anchorages at the interface, the repaired beam was not suddenly failed after the peeling and the shear strength was almost equivalent to that of the sound concrete specimen. The beam specimen repaired by the proposed method did not show the peeling at the interface until failure, and then it provided the almost same shear strength as the sound beam.
