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.

Raw materials for cement manufacturing

Sulphates may be present in clinker up to about 3%. Sulphur in raw materials increases SOx emission and cause build-up in preheater. Sulphate can form a stable compound with Potassium (K2SO4) and to lesser extent Sodium (Na2SO4). The sulphates in the clinker comes from raw materials and fuel.

About this site

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 kiln stage.
