Abstract:This paper examines the test results from a research program that evaluated the performance of epoxy coatings as a corrosion prevention method. In this study, laboratory tests were performed on small-scale precracked reinforced concrete specimens containing epoxy-coated reinforcement. A total of six different epoxy coatings with four duplicate bars for each coating type were evaluated. The concrete specimens were subjected to a simulated marine environment for more than five years and corrosion current density of the steel reinforcement was measured using Linear Polarisation Resistance technique. At the end of the testing period it was found that epoxy coating is an effec- tive method to prevent corrosion of steel reinforcing bars in cracked high w/c concrete. It was also found that pretreatment of the steel surface before the coating application enhances the effectiveness of epoxy coatings as steel corrosion prevention measure.
