Summary:
Tests were conducted using 10 cm. (3.93 in.) lengths of both epoxy coated and bare steel reinforcing rods in simulated concrete environments of varying pH and chloride ion levels. Polarization studies using cathodic scan techniques were used to characterize the quality of the epoxy coating. In all the environments tested, bars with more defects required larger currents at a given potential than did the bars with few defects. Corrosion potential measurements in passive environments showed significant fluctuations from day to day, making it difficult to use potential measurement for corrosion characterization. Galvanic couples between epoxy coated and uncoated bars indicated that galvanic currents increased as the differences in the corrosion potentials increased and also as the chloride ion content of the environment increased from 0 to 0.05 M.
