Abstract

The electrolytic processes in the ASTM C 1202 chloride penetration test method have been reexamined both theoretically and experimentally. The analyses show that hydroxyl (OH) ion generated at the cathode during testing carries a substantial part of the current and that chloride (Cl) ion is not the sole current carrier. Attention has also been drawn to the implication of the experimental results on the determination of the Cl ion diffusivity by the ASTM C 1202 experimental setup.
