| A1.3 Significance and Use
A1.3.1 This test method provides analytical procedures to determine the major chemical constituents of limestone (see Note 1). The percentages of specific constituents that determine a material’s quality or fitness for use are of significance depending upon the purpose or end use of the material. Results obtained may be used in relation to specification requirements. Note A1.1: This test method can be applied to other calcareous
materials if provisions are made to compensate for known
interferences.

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
201.2R, 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 Test Method
D516 or Test Method
D4130. Percent sulfate by
mass in soil can be determined by Test Method 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 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. 1.5 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. 1.6 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. |
