Cement clinker Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement

Clinker C3S paramount International Cement Review

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.
