1.1 These test methods are used to determine the consistency of concrete by the Vebe consistometer apparatus and the density of the consolidated concrete specimen. These test methods are applicable to freshly mixed concrete, prepared in both the laboratory and the field, having a nominal maximum size aggregate of 50 mm (2 in.) or less. If the nominal maximum size of aggregate is larger than 50 mm (2 in.), the methods are applicable only when performed on the fraction passing the 50-mm (2-in.) sieve with the larger aggregate being removed in accordance with Practice C172.
1.2 These test methods, intended for use in testing roller-compacted concrete, may be applicable to testing other types of concrete such as cement-treated aggregate and mixtures similar to soil-cement.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information purposes only.
1.4 This standard does not purport to address all of the safety problems, 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.
