Multiple Corrosion-Protection Systems for Reinforced Concrete Bridge Components
This is a summary of a Federal Highway Administration project that is fully documented in a separate report under the same title. Epoxy-coated reinforcement (ECR) is the principal concrete reinforcing material currently in use in corrosive environments in the United States. The purpose of this study was to evaluate methods for making ECR more corrosion resistant by using multiple corrosion-protection strategies in bridge decks and bridge members in marine environments where salt, moisture, and high temperatures are prevalent. The research was conducted using laboratory and large field test specimens, and the results were 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 was 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.
