MECHANICAL ACTIVATION OF FLY ASH: PHYSICAL, MINERALOGICAL AND MORPHOLOGICAL CHARACTERIZATION OF GROUND FLY ASHES

Sedef DİKMEN [1] , Zafer DİKMEN [2] , Gülgün YILMAZ [3] , Seyhan FIRAT [4]


In this study, physical, mineralogical and morphological characteristics of mechanically treated fly ashes are investigated. The compositional analysis of the raw fly ash was determined using X-ray fluorescence (XRF) technique. The XRD patterns reveal that the main phase quartz along with mullite and anhydrite. The raw fly ash was also wet ground using a laboratory mill, for several different times (from 2 to 16 hours) in order to examine how the grinding increases the activity of the fly ash. The ground fly ash was characterized for (i) particle size distribution: laser diffraction method, (ii) specific surface area: BET-method, (iii) crystalline structure: X-ray diffractometer, and (iv) morphology of particles: scanning electron microscope. According to physical characterization, fineness increasing of samples with grinding time was observed, but loss of effectiveness occurred for grinding time longer than 12 hours. In addition, the unmilled fly ash showed lower specific surface area, due to the presence of cenospheres in the original fly ash. Only a little change in crystalline structure of fly ashes was observed when grinding and there were changes in the area and height of each diffraction peak.
