- Abstract
- The possibilities of protecting steel reinforcing bars embedded in concrete of bridge decks from corrosion by using organic barrier-type coatings are being investigated in this project. This corrosion is accelerated by the chloride ions of the two most commonly applied deicing materials, sodium chloride and calcium chloride. In this report, physiochemical studies performed on coatings and coated bars are discussed, including immersion studies of coatings in corrosive solutions.
