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.

In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

The majority of carbon dioxide emissions in the manufacture of Portland cement (approximately 60%) are produced from the chemical decomposition of limestone to lime, an ingredient in Portland cement clinker. These emissions may be reduced by lowering the clinker content of cement.

Afterward, the clinker is cooled, and cement plants grind it where it mixes with small amounts of limestone and gypsum. Cement is too fine, for example,1 pound of cement contains 150 billion grains. Finally, the cement is ready for transport to ready-mix concrete companies to be habitual in a multiplicity of construction projects.

One way for Lafarge to emit less carbon dioxide (CO2) is to use alternative raw materials to replace limestone in the manufacture of cement. Derived from natural or industrial sources, such alternatives have the same properties as clinker, the main ingredient in conventional cement.
