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.

Keywords:
electrolyte processes, chloride, hydroxyl
