1.1本规程涵盖了当规程C31中所述的标准捣棒和内部振动程序不可行时，从混凝土中制备圆柱形试样的程序。本规程适用于在实验室和现场制备的标称最大骨料尺寸为50 mm（2 in.）的新拌混凝土或更少。如果标称最大粒径骨料大于2英寸。，该规程仅适用于通过50 mm（2-in.）的部分按照规程C172的要求，筛去较大骨料。本规程用于测试碾压混凝土，可适用于测试其他类型的混凝土，如水泥处理骨料和类似于水泥土的混合物。 1.2使用振动台制作混凝土筒有两种方法: 1.2.1方法A是在连接到振动台的可重复使用的钢模具中制作试样的程序。 1.2.2方法B是在一次性塑料模具中制作试样的程序，该模具已插入连接至振动台的金属套筒中。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.4本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

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.
