Abstract:

The objective of this research project is to investigate the corrosion and bond performance of different coatings and nontraditional metals in salt-contaminated concrete. An accelerated macrocell corrosion test is being carried out to determine the behavior of galvanized, stainless steel-clad, epoxy-coated, PVC-coated, nylon-coated, and 304 stainless steel reinforcing bars cyclically exposed to a chloride solution. To date, there has been no change in the readings to indicate that corrosion of the reinforcement has initiated. Pullout testing was conducted to compare the bond behavior of bars with different polymer coatings. There were not any significant differences observed in the bond behavior of the epoxy, PVC, and nylon coatings. Each coating type was able to achieve a similar maximum applied pullout force and exhibited similar load–slip behavior during testing.
