ASTM C 1952 : 2025

1.1This test method covers the determination of the bulk electrical resistivity of hardened mortar cubes conditioned in lime-saturated water in order to provide a rapid indication of the development of the volume and continuity of pore structure. This test is conducted on the same mortar cubes used testing for compressive strength.

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

1.3The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)3

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
