Performance of Fusion-Bonded Epoxy-Coated Steel Reinforcment

Standard production steel reinforcement protected with a fusion-bonded epoxy coating has been subjected to accelerated testing on a natural exposure site over a 5-year period alongside plain steel and galvanised steel in purpose-designed concrete specimens. The epoxy coating provided considerable protection to the steel for the length of the trial when exposed in concrete with a high concentration of added chloride leading to significant practical advantage. However, the use of these coatings in practice does not provide complete protection since corrosion was observed to be spreading from points of defect in the coatings when the steel was embedded in concretes containing high levels of chloride.
