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.

Portland cement - Wikipedia

It was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of Portland cement are available.

The Advantages of Portland-Limestone Cement| Concrete ...

The limestone is more easily ground than the clinker, which is harder, and becomes concentrated in the finest particles. Overall fineness must be higher (for equivalent performance) for fineness of the clinker fraction to be similar to OPC. This means the production rate is slowed and some additional grinding energy is required.
