Reexaminawtion of ASTM C 1202-Standard Test Method for Electrical Indication of Concrete's Ability to Resist Chloride Ion Penetration

摘要

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, AWttention has also be4en drwn to the implication of the experimental results on the determination of the Cl~- ion diffusivity by the ASTM C 1202 experimental setup.
