1 Scope This document describes the reference washing and dry sieving method used for testing and in case of dispute, for determination of the particle size distribution of aggregates . Other methods can be used provided that an appropriate working relationship with the reference method has been established. It applies to all aggregates , including lightweight aggregates , up to 90 mm nominal size, but excluding filler. NOTE Dry sieving without washing can be used for aggregates free from particles which cause agglomeration.

1.1 This specification covers coal ash and raw or calcined natural pozzolan, for use in concrete where cementitious or pozzolanic action, or both, is desired, or where other properties normally attributed to coal ash or natural pozzolans may be desired, or where both objectives are to be achieved. NOTE 1—Finely divided materials may tend to reduce the entrained air content of concrete. Hence, if a coal ash or natural pozzolan is added to any concrete for which entrainment of air is specified, provision should be made to ensure that the specified air content is maintained by air content tests and by use of additional air-entraining admixture or use of an air-entraining admixture in combination with airentraining hydraulic cement. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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. 1.1 本规范涵盖煤灰和生的或煅烧的天然火山灰，用于需要水泥质或火山灰作用或两者兼有的混凝土，或者可能需要通常归因于煤灰或天然火山灰的其他特性的混凝土，或者需要这两个目标的地方 要实现。 注 1——细碎材料可能会降低混凝土夹带的空气含量。 因此，如果将煤灰或天然火山灰添加到指定夹带空气的任何混凝土中，则应采取措施确保通过空气含量测试和使用额外的引气剂或使用 引气剂与引气水凝水泥的组合。 1.2 以 SI 单位表示的值被视为标准值。 本标准不包括其他计量单位。 1.3 本标准正文引用了注释和脚注，提供了解释性信息。 这些注释和脚注（不包括表格和数字中的注释和脚注）不应视为标准的要求。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的国际标准、指南和建议制定原则的决定中确立的国际公认的标准化原则制定的。
