1.1 本规范适用于混凝土混合物中使用的磨碎的碳酸钙（GCC是一种磨碎的石灰石）和其他细骨料矿物填料（AMF）材料。本规范规定了混凝土中使用的GCC和AMF材料的类型。 1.2 如果使用中的混凝土暴露在硫酸盐中，则除非使用缓解方法，否则不应使用源自地面石灰石的填料。 注1: 美国混凝土协会（ACI）技术文件201.2R、318、332和350包含了有关使用中硫酸盐暴露的有用信息和规范要求。 可根据试验方法测定水中的可溶性硫酸盐 D516 或测试方法 D4130 .土壤中硫酸盐的质量百分比可通过试验方法测定 C1580 。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 注2: 筛网尺寸由其在规范中的标准名称确定 E11 括号中给出的备选名称仅供参考，不代表不同的标准筛尺寸。 1.4 本标准的文本引用了提供解释性信息的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应被视为本标准的要求。 1.5 本标准并不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建立适当的安全和健康实践，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====== A1.3 意义和用途 A1.3.1 本试验方法提供了测定石灰石主要化学成分的分析程序（见 注1 )。根据材料的用途或最终用途，决定材料质量或适用性的特定成分的百分比具有重要意义。所获得的结果可用于规范要求。 注A1.1: 如果规定对已知干扰进行补偿，则此试验方法可应用于其他钙质材料。

1.1 This specification applies to ground calcium carbonate (GCC is a type of ground limestone) and other finely divided aggregate mineral filler (AMF) materials for use in concrete mixtures. The specification defines the types of GCC and AMF materials for use in concrete. 1.2 If concrete in service is subject to sulfate exposure, fillers derived from ground limestone should not be used unless mitigation methods are used. Note 1: American Concrete Institute (ACI) technical documents 201.2R, 318, 332, and 350 contain useful information and code requirements dealing with sulfate exposure in service. Soluble sulfate in water can be determined in accordance with Test Method D516 or Test Method D4130 . Percent sulfate by mass in soil can be determined by Test Method C1580 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Note 2: Sieve size is identified by its standard designation in Specification E11 . The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. 1.4 The text of this standard references notes and footnotes, which provide explanatory information. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the 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 and health 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 ====== A1.3 Significance and Use A1.3.1 This test method provides analytical procedures to determine the major chemical constituents of limestone (see Note 1 ). The percentages of specific constituents that determine a material’s quality or fitness for use are of significance depending upon the purpose or end use of the material. Results obtained may be used in relation to specification requirements. Note A1.1: This test method can be applied to other calcareous materials if provisions are made to compensate for known interferences.
