ASTM C1800/C1800M-16 PDF Download

ASTM C1800/C1800M-16 is a standard test method that describes how to determine the density of roller-compacted concrete (RCC) specimens using a gyratory compactor. The purpose of this test method is to prepare specimens with a maximum aggregate size of up to 37.5 mm and a Vebe consistency time greater than 30 s. It is important to note that this method does not specify a standard compactive effort in RCC mixture design, but it provides a standardized way to compare different aggregate combinations.

This test method can be used for making specimens and determining densities of laboratory-produced RCC mixtures. However, it is recommended that the agency and personnel performing this test method meet the criteria of Practice C1077 or an equivalent standard. Additionally, it is worth mentioning that using gyratory-compacted RCC specimens for strength determinations is not recommended due to the specimen geometry and low L/D (length/diameter) ratios. Research has shown a lack of correlation between compressive strengths of gyratory-compacted RCC specimens and specimens prepared according to Practice C1435/C1435M.

The test method covers the compaction of cylindrical specimens of RCC using the gyratory compactor to determine density. The standard allows for the use of either SI units or inch-pound units, but it is important to use either system independently as combining values from both systems may result in non-conformance with the standard.
