1.1本试验方法旨在测试碾压混凝土样本，并涵盖在多种提升形式的施工中测定硬化混凝土层之间的相对粘结力。它适用于所有类型的分层混凝土结构，包括上层混凝土或砂浆粘结到下层混凝土或砂浆，其中总深度足以满足本试验方法的最小试样长度和直径要求。 注1-本试验方法不提供受试材料的抗拉强度结果。 1.2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。 1.3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 test method is intended for testing roller-compacted concrete specimens and covers determination of the relative bond between layers of hardened concrete in multiple-lift forms of construction. It is applicable to all types of layered concrete construction involving an upper layer of concrete or mortar bonded to an underlying layer of concrete or mortar where the total depth is sufficient to meet the minimum specimen length and diameter requirements of this test method. Note 1-This test method does not provide tensile strength results of the material tested. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 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.
