- Scope
- 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 This specification covers coal ash and raw materials or calcined natural pozzolans, for use in concrete where cementitious or pozzolanic action, or both, may be required, or where other properties usually attributed to coal ash or natural pozzolans may be required, or where both objectives are required. accomplish. NOTE 1—Finely crushed materials may reduce the air content of the concrete. Therefore, if coal ash or natural pozzolans are added to any concrete that is specified to entrain air, steps should be taken to ensure that it passes the air content test and the use of additional air-entraining agents or the use of a combination of air-entraining agents and air-entraining hydraulic cement. 1.2 Values expressed in SI units are considered standard values. This standard does not cover other units of measurement. 1.3 The text of this standard references notes and footnotes to provide explanatory information. These notes and footnotes (excluding those in tables and figures) should not be considered requirements of the standard. 1.4 This International Standard was developed in accordance with the internationally recognized principles of standardization established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the Technical Barriers to Trade (TBT) Committee of the World Trade Organization.
