1.1 This test method covers the determination of density and air content of freshly mixed roller-compacted concrete using the apparatus described in Test Method C231/C231M and the vibrating hammer described in Test Method C1435/C1435M. 1.2 The text of this test method references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard. 1.3 Units--The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. NOTE 1-Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. 1.4 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 before use. (WarningFresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)
This standard will be used in the design of roller-compacted concrete (RCC) mixtures and to aid in controlling the quality of those mixtures during RCC construction.
