1.1 This test method covers the determination of the bulk electrical conductivity of saturated specimens of hardened concrete to provide a rapid indication of the concrete's resistance to the penetration of chloride ions by diffusion (See Note 1). The results of this test method can be related to the apparent chloride diffusion coefficient that is determined using Test Method C1556.

Note 1—The term bulk is used because the electrical conductivity is determined by measuring the current passing through all the phases of a test specimen (e.g., cement paste, sand, aggregate). This is accomplished using electrodes that cover the ends of the specimen. Other test methods that measure conductivity may use probes placed on the side surface of the specimen.

1.2 UnitsThe values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. (WarningFresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure. )
