Investigation of glycerol polymerization in the clinker ...

Calcination of a mixture of calcareous and argillaceous materials comprising limestone, sand, clay and iron ore at a temperature of about 1400–1500 °C produces a sintered nodular material called “clinker”, whose major components are tricalcium silicate (typically about 65% of the total), dicalcium silicate (about 15% of the total), tricalcium aluminate (typically about 7% of the total) and tetracalcium aluminoferrite

Cement clinker - Wikipedia

Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall. Organic compounds are also often added as grinding aids to avoid powder agglomeration.
