Abstract: 
Corrosion of steel rebar is the most common source of degradation in reinforced concrete structures of marine environments. The effect of plain reinforcement corrosion on the flexural response of Post Tensioned (PT) concrete structures is, however, not fully assessed yet. This paper presents the results of an experimental study involving the flexural behavior of sound, deteriorated and repaired PT beams under monotonic loading. The effect of concrete removal from the beam due to the corrosion of reinforcing bars and the efficiency of high performance patch repair for restoring the load-bearing capacity of deteriorated beam have been investigated. It was found that repairing with high performance concrete can enhance the structural performance of deteriorated PT beams with non-corroded tendons.
