Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEThe designation was corrected editorially in September 2016.1. Scope1.1 This specification applies
3、 to ground calcium carbonate(GCC is a type of ground limestone) and other finely dividedaggregate mineral filler (AMF) materials for use in concretemixtures. The specification defines the types of GCC and AMFmaterials for use in concrete.1.2 If concrete in service is subject to sulfate exposure,fill

Soluble sulfate in watercan be deter
5、mined in accordance with Test Method D516 or Test MethodD4130. Percent sulfate by mass in soil can be determined by Test MethodC1580.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.NOTE 2Sieve size is identified by its stand

These notes and foot-notes (exclud
7、ing those in tables and figures) shall not beconsidered as requirements of the standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

Research has demonstratedthat the use of GCC results in improved packing density andthe GCC parti
21、cles provide nucleation sites that increase the rateof hydration of hydraulic cementitious materials. The effect ofhydration is also influenced by the particle size distribution(PSD) and fineness of the GCC. See cited References (1-6).54. Classification4.1 Types A and B, which are derived from calci
