1.1 本规范涵盖了根据规范制造的大多数形式的纤维增强混凝土 C94/C94M 或规范 C685/C685M 如本文所修改的。它不包括交付给买方后纤维增强混凝土的浇筑、固结、养护或保护。 1.2 本规范的某些章节也适用于拟通过干混喷射混凝土或零坍落度喷射混凝土的纤维增强混凝土，以及用于制造预制构件的纤维加强混凝土。在这些情况下，涉及配料装置、搅拌设备、搅拌和输送以及可加工性和空气含量测量的章节不适用。 1.3 本规范不包括由ASTM小组委员会C27.40管辖的通过喷涂工艺制造的薄截面玻璃纤维增强混凝土。 1.4 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不得组合。 1.5 如果从另一个标准获得的所需结果没有以本标准使用的相同单位制报告，则允许使用SI快速参考指南中的转换系数转换这些结果。 2. 1.6 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。 警告-- 新鲜的水硬性水泥混合物具有腐蚀性，长时间暴露可能会对皮肤和组织造成化学灼伤。） 3. 1.7 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。

1.1 This specification covers most forms of fiber-reinforced concrete manufactured in accordance with Specification C94/C94M or Specification C685/C685M as modified herein. It does not cover the placement, consolidation, curing, or protection of the fiber-reinforced concrete after delivery to the purchaser. 1.2 Certain sections of this specification are also applicable to fiber-reinforced concrete intended for shotcreting by the dry-mix or to zero-slump, and fiber-reinforced concrete used to manufacture precast elements. In these cases, the sections dealing with batching plant, mixing equipment, mixing and delivery, and measurement of workability and air content, are not applicable. 1.3 This specification does not cover thin-section glass fiber-reinforced concrete manufactured by the spray-up process that is under the jurisdiction of ASTM Subcommittee C27.40. 1.4 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. 1.5 If required results obtained from another standard are not reported in the same system of units as used by this standard, it is permitted to convert those results using the conversion factors found in the SI Quick Reference Guide. 2 1.6 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.) 3 1.7 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.
