ASTM C Rapid Chloride Permeability Test. T E C H N I C A L. B U L L E T I N T B – 0 1 0 0. Concrete. Introduction. This test method was originally developed. Full-Text Paper (PDF): ASTM C rapid chloride penetrability test: a new look. The ASTM C rapid chloride permeability test, which is widely used, quickly determines how resistant your concrete is to chloride ingress.

Most concretes, if properly cured, become progressively and significantly less permeable with time. The anticipated exposure conditions and time before a structure will be put into service should be considered. When using this test for determining acceptability of concrete mixtures, statistically-based criteria and test age for prequalification, or for acceptance astm c1202 on jobsite samples, should be stated in project specifications.
Other specimen diameters may be tested with appropriate changes in the applied voltage cell design see 7. This includes specimens with actual diameters ranging astm c1202 95 to mm.
Astm c1202 Item s – proposed revisions of this standard. When this method is used for mixture qualification and acceptance testing, it is imperative that the curing procedures and the age at time of testing be clearly specified.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Acceptance criteria for this test should consider the sources of variability affecting the results and ensure balanced risk between supplier and purchaser. These notes and footnotes excluding those in tables and astm c1202 shall not astm c1202 considered as requirements of the standard.
One approach to establishing criteria is discussed in Ref 6. Astm c1202 Documents purchase separately The documents listed below are referenced within the subject standard but are not provided qstm astm c1202 of the standard. No other units of measurement are included in this standard.
The results from this test on some such concretes indicate low resistance astm c1202 chloride ion penetration, while day chloride ponding tests on companion slabs astm c1202 a higher resistance. For specimens with diameters less than 95 mm, particular care must be taken in coating and mounting the specimens to ensure that the conductive solutions are able to contact the entire end areas during the test.
In most cases the electrical conductance results have shown good correlation with chloride ponding tests, such as AASHTO T, on companion slabs cast from the same concrete mixtures Refs astm c1202 5.
