Abstract

Corrosion is the major source of degradation in reinforced concrete structures, particularly in harsh environmental conditions. In literature, a number of research works has been carried out on the performance evaluation of the post-tensioned (PT) beams with the corroded PT cables, but very few are related to the PT beams with corroded plain reinforcement before and after applying repair. In this paper, the flexural behaviors of intact, corroded/deteriorated, and repaired PT beams are examined. In particular, the effects of patch repair with and without applying epoxy at the repair-substrate interface have been investigated. Based on the results, using high performance concrete materials as a patch-repair without epoxy at the repair-substrate interface applying can significantly re-store the structural performance of deteriorated PT beams.
