The possibilities of protecting steel reinforcing bars embedded in concrete 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 used deicing materials, calcium chloride and sodium chloride. In this report, corrosion studies carried out on coated reinforcing bars embedded in concrete are discussed. Methods of instrumenting creep-test specimens are also explained. The electrical potentials of coated reinforcing bars are not reliable indicators of the corrosion state of the steel bars. The electrical resistances of the coating films are more reliable indicators of the performance of a coating material than the electrical potential measurements.
