Surface Resistivity of Concrete AASTHO T358.
The AASTHO T358 test method covers the determination of the electrical resistivity of water-saturated concrete to provide a rapid indication of its resistance to the penetration of chloride ions. The test method is applicable to types of concrete where correlations have been established between the test procedure and long-term chloride diffusion procedures such as those described in ASTM C1556.
This test method covers the laboratory evaluation of the electrical resistivity of concrete samples to provide a rapid indication of their resistance to chloride ion penetration. Wenner probe measurements have shown good correlations with other electrical indication tests such as the T 277 and the ASTM C1202 tests. In most cases, the electrical resistivity results have shown good correlation with chloride exposure tests, such as ASTM C1556, on companion cylinders cast from the same concrete mixtures.
This test method is suitable for evaluation of materials and material proportions for design purposes, as well as for research and development.
