"Originally developed to enhance the bond between concrete and steel, reactive enamel coatings have shown great promise in protecting steel from corrosive environments. However, the corrosion resistance of the material has not yet been tested beyond 40 days. Moreover, when the material was tested, it was applied to smooth steel pins, not deformed steel bars which are commonly used in reinforced concrete structures. Therefore, this study focused on the corrosion resistance of three different enamel coatings, along with a standard epoxy coating, each of which were applied to both smooth and deformed steel bars and included both short-term and long-term test methods. The three enamel coatings tested within this study were: reactive enamel, pure enamel, and double enamel. The reactive enamel was obtained by combining pure enamel with calcium silicate (cement) at a 1-to-1 ratio by weight. The double enamel was composed of an inner layer of pure enamel and an outer layer of reactive enamel. Each coating was subjected to a modified ASTM B117 salt spray test and a potentiostatic polarization test that followed the Accelerated Corrosion Test (ACT) Method. In addition to these two tests, the corrosion resistance of the reactive enamel coating was also evaluated through a modified AASHTO T-259 ponding test, which included periodic resistivity and half-cell measurements. Results obtained from the tests revealed that the pure and double enamel coatings provided a superior amount of protection when compared to the 50/50 enamel coating. However, the overall performance of the pure and double enamel coatings was limited by the manufacturing process, which resulted in significant variations in coating thickness"--Abstract, page iii.
