Abstract:
This study was undertaken to ascertain the feasibility of using organic coatings, especially epoxies, to protect steel reinforcing bars embedded in concrete of bridge decks from rapid corrosion. This corrosion is caused by chloride ions from the deicing salts, sodium chloride and calcium chloride. Altogether, 47 different coatings were evaluated to some extent, of which 36 were epoxy coatings.
