Portland cement clinker - Understanding Cement

Portland cement clinker - overview. 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 setting properties. This page gives a thumbnail sketch.

Clinker C3S paramount

MgO will enter solid solution in the clinker minerals substituting for CaO, and thereby raising the lime saturation somewhat. However, there is some evidence that MgO can promote the C3S in clinker being in one of the less reactive monoclinic crystal forms and that this can severely reduce early strength development of cement made from the clinker.
