    WK36906

    1. Scope

    1.1 This Specification applies to ground calcium carbonate (GCC is a type of ground limestone) and other finely divided aggregate mineral filler (AMF) materials for use in concrete mixtures. The Specification defines the types of GCC and AMF materials for use in concrete. 1.2 If concrete in service is subject to sulfate exposure, fillers derived from ground limestone should not be used unless mitigation methods are used. Note 1 American Concrete Institute (ACI) technical documents 201, 318, 332, and 350 contain useful information and code requirements dealing with sulfate exposure in service. Soluble sulfate in water can be determined in accordance with ASTM D516 or ASTM D4130. Percent sulfate by mass in soil can be determined by ASTM C1580. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Note 2 Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. 1.4 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. 1.5 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.

    Currently, there are no ASTM specification standard for the use of ground limestone and other finely divided materials in concrete that the American Concrete Institute, concrete suppliers, aggregate producers, and governmental agencies can reference in specification documents or quality control manuals.
