The Rapid Chloride Permeability Test and Its Correlation to the 90-Day Chloride Ponding Test

Abstract

This paper reviews documents referenced by ASTM C1202, Electrical Indication of Concrete's Ability to resist Chloride Ion Penetration, and explores the correlation of ASTM C1202 to AASHTO T259, Resistance of Concrete to Chloride Ion Penetration. Based on the review of the documents referenced in ASTM C1202, it is concluded that reliable and proper correlations do not exist between the rapid test procedure results and 90-day ponding test results. The ASTM C1202 or AASHTO T277 test procedures should not be used in specifications without proper correlation to long-term tests. It is recommended that the table relating chloride penetration to coulomb values in these test procedures be removed since it is inaccurate and can be misleading.
