Abstract
The electrolytic processes in the ASTM C 1202 chloride penetration test met hod have been reexamined both theoretically and experimentally. The analyse s show that hydroxyl (OH-) ion generated at the cathode during testing carr ies a substantial part of the current and that chloride (Cl-) ion is not th e sole current carrier. Attention has also been drawn to the implication of the experimental results on the determination of the Cl- ion diffusivity b y the ASTM C 1202 experimental setup.
