Abstract There is a need to develop a better understanding of the relationship among short- medium- and long-term tests to assess the resistance of concrete to chloride penetration. Should you want CTLGroup to fabricate specimens using your materials for this test, contact one of the contacts below to discuss specifics.
In this contribution, a resistivity-based test is compared to a day salt ponding test.
Use Used to evaluate concretes or products ability to reduce the ingress of chlorides into concrete. Recommended articles Citing articles 0.

The day salt ponding test can be improved by using a depth of penetration approach rather than an integral chloride content and by limiting the transport process to diffusion only. Comparative testing is presented for several concrete and mortar mixtures, which suggests that if modifications are made to test procedures and methods of analysis then the relationship between the results of the resistivity-based test and the diffusion-based test is improved.
Re-evaluation of the AASHTO T day salt ponding test – ScienceDirect
The short-term 6-h rapid chloride permeability test has been criticized for its lack of a scientific basis and poor correlation to the so-called control ponding test. Proposed mix designs, aasnto used in evaluation of sealers, coatings, epoxies.
