• Abstract:
  The various sources and consequences of damage to epoxy-coated reinforcement were studied. For inspection of damage before placement, holiday detectors were evaluated. Potential damage, resulting from concreting operations such as placement and consolidation, was investigated. To examine the quality of the coating following application, a hot water bath test was evaluated. Finally, corrosion performance of the epoxy-coated reinforcement was evaluated by cyclic immersion of bars with different damage levels in a saltwater solution. Based on the findings, recommendations are provided for modifying current inspection, fabrication, patching, and placement procedures.
