1.1 这些试验方法包括测定耐化学性砂浆、灌浆、整体表面处理和聚合物混凝土的抗压强度。这些材料可以基于树脂、硅酸盐、二氧化硅或硫粘合剂。 1.2 试验方法A概述了通常用于骨料尺寸小于0.0625 in.（1.6 mm）的系统的试验程序。试验方法B涵盖了通常用于含有0.0625骨料的系统的试验程序 英寸至0.4英寸（1.6 毫米至10毫米）。试验方法C用于含有大于0.4英寸骨料的系统。 1.3 这些测试方法提供了两种不同的方法来控制测试速率。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者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。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 这些试验方法提供了一种测定耐化学性砂浆、灌浆、整体表面处理和聚合物混凝土抗压强度的方法。

1.1 These test methods cover the determination of the compressive strength of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes. These materials may be based on resin, silicate, silica, or sulfur binders. 1.2 Test Method A outlines the testing procedure generally used for systems containing aggregate less than 0.0625 in. (1.6 mm) in size. Test Method B covers the testing procedure generally used for systems containing aggregate from 0.0625 in. to 0.4 in. (1.6 mm to 10 mm) in size. Test Method C is used for systems containing aggregate larger than 0.4 in. 1.3 These test methods provide two different methods for controlling the testing rate. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 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. 1.6 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 ====== 4.1 These test methods offer a means of determining the compressive strength of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.
