Portland cement clinker - Understanding Cement

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the

2005-3-1  The milling time was selected to maintain the specific surface area within the range used in normal cements. The milled clinkers were characterized using the following techniques: Blaine specific surface area (ASTM C204); PCE, ASTM C24; and X-ray diffraction (XRD). Clinkering reaction progress and hydration were followed through DTA/TG.
