Chloride penetration resistance

Description:No other units of measurement are included in this standard. The results from this test on some such concretes indicate low resistance to chloride ion penetration, while day chloride ponding tests on companion slabs show a higher resistance. The anticipated exposure conditions and time before a structure will be put into service should be considered. One approach to establishing criteria is discussed in Ref 6. Acceptance criteria for this test should consider the sources of variability affecting the results and ensure balanced risk between supplier and purchaser. Most concretes, if properly cured, become progressively and significantly less permeable with time. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
