Additional information

1.1 This specification covers coal fly 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 fly ash or 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 fly 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 air-entraining 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. |
