    ASTM C1240

    1. Scope

    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 values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    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 and health 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.
