Significance and Use
4.1 This Test Method is used to prepare specimens containing a nominal maximum aggregate size of up to 37.5 mm [1-1/2 in.] and a Vebe consistency time, in accordance with Test Method , of greater than 30 s for determining the density of compacted RCC mixtures. This method is not intended to specify a standard compactive effort in RCC mixture design, but rather to provide a standardized method for comparing various aggregate combinations.
4.2 This test method may be used for making specimens and determining densities of laboratory-produced RCC mixtures.
Note 1: The agency and personnel performing this test method should meet the criteria of Practice or equivalent.
Note 2: The use of gyratory-compacted RCC specimens for strength determinations is not recommended due to specimen geometry and low L/D ratios. Research has shown a lack of correlation between compressive strengths of gyratory-compacted RCC specimens and specimens prepared in accordance with Practice .
1.1 This test method covers the compaction of cylindrical specimens of roller-compacted concrete (RCC) using the gyratory compactor to determine density.
1.2 Units—The values stated in 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.
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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)
