Standard Practice for Making Roller-Compacted Concrete in Cylinder Molds Using a Vibrating Table
1.1 This practice covers procedures for making cylindrical test specimens from concrete when the standard procedures of rodding and internal vibration, as described in Practice C31, are not practicable. This practice is applicable to freshly mixed concrete, prepared in the laboratory and the field, having a nominal maximum size aggregate of 50 mm (2 in.) or less. If the nominal maximum size aggregate is larger than 2 in., the practice is 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. This practice, 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.
1.2 Two methods are provided for making concrete cylinders using a vibrating table:
1.2.1 Method A is a procedure for making test specimens in steel reusable molds attached to a vibrating table.
1.2.2 Method B is a procedure for making test specimens in single-use plastic molds that have been inserted into a metal sleeve attached to a vibrating table.
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.
