  • On-line X-ray diffraction for quantitative phase analysis

    On-line X-ray diffraction for quantitative phase analysis

    Portland cement is prepared by grinding the clinkers in a ball mill with approximately 5 wt. % each of gypsum (CaSO 4.2H 2 O) and limestone. The mill temperature rises to about 130 C during grinding, causing partial decomposition of the gypsum to form hemihydrate (CaSO 4.0.5H 2 O) and occasionally anhydrite (CaSO 4).
