1.1本规范涵盖了用作混凝土和砂浆中胶凝材料的矿渣水泥的三个强度等级。 注1 — 本规范中描述的材料可用于与波特兰水泥混合，以生产符合规范要求的水泥 C595 或作为混凝土或砂浆混合物中的单独成分。该材料也可用于各种特殊灌浆和砂浆，当与适当的活化剂一起使用时，作为某些应用中的主要胶结材料。 注释2 — 本规范中所述材料使用的技术方面的信息包含在 附录X1 , 附录X2 和 附录X3 . 关于该主题的更多详细信息载于ACI 233R-03。 2. 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。 在文本中，英寸-磅单位显示在括号中。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。当实际中未使用英寸-磅单位时，数值仅以国际单位制表示。 1.3 以下安全隐患警告仅适用于本规范中描述的测试方法。 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和健康实践，并确定监管限制的适用性。 1.4本标准的文本引用了提供解释信息的注释和脚注。这些注释和脚注（不包括表中的注释和脚注）不应视为本标准的要求。

1.1 This specification covers three strength grades of slag cement for use as a cementitious material in concrete and mortar. Note 1 — The material described in this specification may be used for blending with portland cement to produce a cement meeting the requirements of Specification C595 or as a separate ingredient in concrete or mortar mixtures. The material may also be useful in a variety of special grouts and mortars, and when used with an appropriate activator, as the principal cementitious material in some applications. Note 2 — Information on technical aspects of the use of the material described in this specification is contained in Appendix X1 , Appendix X2 , and Appendix X3 . More detailed information on that subject is contained in ACI 233R-03. 2 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Values are stated in only SI units when inch-pound units are not used in practice. 1.3 The following safety hazards caveat pertains only to the test methods described in this specification. 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. 1.4 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables) shall not be considered as requirements of this standard.
