| Abstract | Epoxy-coated reinforcement (ECR) is the principal concrete reinforcing material currently in use in the United States in corrosive environments. The purpose of this study is to evaluate methods for making ECR more corrosion resistant by using multiple corrosion protection strategies in bridge decks, as well as for bridge members in marine environments where abundant salt, moisture, and high temperatures are prevalent. This research is being conducted using laboratory and field tests, the results of which will be used to compare the performance of the corrosion protection systems on the basis of chloride threshold, corrosion rate, life expectancy, and cost effectiveness. Fusion-bonded thermoset ECR currently is being evaluated in conjunction with inorganic and organic corrosion inhibitors, bars coated with zinc prior to the application of epoxy, and chemical pretreatments and epoxy formulations that increase the adhesion of the epoxy coating to the reinforcing steel. |
