1.1 本试验方法包括测定预浇筑骨料（PA）混凝土的水硬性水泥浆的抗压强度。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.3 本标准并非旨在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、健康和环境实践，并确定监管限制的适用性。 警告- 新鲜的水硬性胶结混合物具有腐蚀性，长时间接触可能会导致皮肤和组织化学烧伤。 2. 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法提供了一种测定灌浆抗压强度的方法，该灌浆在部分或全部约束条件下膨胀和硬化。 5.2 它特别适用于测定与PA混凝土的灌浆一起使用的灌浆流化剂对抗压强度的影响（见规范） C937 ).

1.1 This test method covers the determination of the compressive strength of hydraulic cement grout for preplaced-aggregate (PA) concrete. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Warning— Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. 2 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method affords a means for determining the compressive strength of grouts that expand and, in use, harden under conditions of partial to total restraint. 5.2 It is particularly applicable for determining the effect on compressive strength of grout fluidifier to be used with grout for PA concrete (See Specification C937 ).
