Abstract:

Coating damage to epoxy-coated rebars (ECR) in chloride-contaminated concrete may lead to failure of the coating protection system. Damage to epoxy coating can occur during the stages of coating application, handling, storage, transportation, fabrication, assemblage, and/or concrete placement. Epoxy patching materials are manufactured to repair coating damage. In earlier corrosion studies at the University of Texas at Austin, performance of patched damaged areas in chloride contaminated concrete specimens and in ECR samples submersed in NaCl solution was marginal. Patching delayed but did not prevent the onset of corrosion. Existing ECR specifications do not adequately describe proper repair procedures with patching materials. No systematic study of the efficacy of patching materials and repair procedures has been reported. In this research, performance of several patching materials was investigated.
