In the inter-grinding mode with Clinker Slag Gypsum ground together , the clinker (with Gypsum) gets preferentially ground leaving slag relatively coarser , proper optimization of the distribution of slag in desired size fractions of Cement with or without cement additives could help achieve a clinker factor of around 35 to 40 % .

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 (Ca 3 Al 2 O 6 ), the most reactive mineral phase (exothermic hydration reaction) in Portland clinker.
