Cement clinker - Wikipedia

Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products. A little gypsum (less than 5 wt.%) must be added to avoid the flash setting of the tricalcium aluminate (Ca3Al2O6), the most reactive mineral phase (exothermic hydration reaction) in Portland clinker. It may also be combined with other active ingredients or cement additions to produce other types of cementincluding, following the Europe
