20、al and physical requirements.3.2.1.1 DiscussionAMF 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
21、 mechanical and fluidtransport properties 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 mate
22、rial consisting predominantly of calcium 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 distribu
23、tion. Research has demonstratedthat the 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 o
24、f the GCC. See cited References (1-6).54. Classification4.1 Types A and B, which are derived from calciumcarbonates, are ground products from quarried stone. Thechemical and physical properties shall comply with the require-ments in Table 1.4.2 Type C is typically a byproduct from the crushing ofqua
25、rried stone, with mineral composition that depend on thestone from which it is derived. 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 divid
26、ed mineralproduct at least 65 % of which passes the 75-m (No. 200) sieve. Thisspecification establishes requirements for GCC and AMF materials thatmeet this definition.5.
