1.1 This specification covers silica fume for use in concrete and other systems containing hydraulic cement.
1.2 In the cases of slurried or densified silica fume, perform the tests on the raw silica fume from which these products have been made.
1.3 The units stated in SI are to be regarded as the standard. No other units of measurement are included in this standard.
1.4 The following safety hazards caveat pertains only to the test methods portions, Sections 10 – 19, of 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Read the material safety data sheets for materials used.
1.5 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.
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.
