17、and Terminology C125.3.2 Definitions of Terms Specific to This Standard:3.2.1 aggregate mineral filler (AMF), na finely dividedinorganic material derived from quarried stone, for use as aningredient in hydraulic cementitious mixtures and meetingspecified chemical and physical requirements.3.2.1.1 Di
18、scussionAMF derived from carbonate or non-carbonate quarried stone are finely divided particulate matterthat have been shown to be effective in improving the particlepacking and rheological characteristics of fresh concrete. Insome cases, enhancement is seen in mechanical and fluidtransport properti
19、es of hardened concrete. AMF for use inconcrete may undergo a series of processing steps such asscreening, grinding, classifying and drying as needed to meetrequirements of this specification.3.2.2 ground calcium carbonate (GCC), na finely dividedinorganic material consisting predominantly of calciu
20、m car-bonate or of the carbonates of calcium and magnesium andmeeting specified chemical and physical requirements.3.2.2.1 DiscussionThe series of processing steps likegrinding and classifying that these products undergo, ensureconsistent particle size distribution. Research has demonstratedthat the
21、 use of GCC results in improved packing density andthe GCC particles 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).5

The chemical and physicalproperties shall comply with the requirements of Table 1.4.3 The Type classification shall be stated by the supplier ofthe product.NOTE 3ACI CT-13 defines mineral filler as a finely divided mineralproduct at least 65% of which
24、 passes the 75-m (No. 200) sieve. Thisspecification establishes requirements for GCC and AMF materials thatmeet this definition.5. General Requirements5.1 The chemical and physical requirements for Type A,Type B, and Type C shall conform to the requirements in Table1.5.2 The purchaser has the author
