Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and nonspecialty was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

The liquid formed both acts as a solvent of ion exchange between the solid phases and draws the reactant particles together by surface tension. The powdery or granular mixture quickly solidifies into spherical nodules of clinker. Cooling and storing. The mixture inside the slightly inclined kiln is rapidly cooled from 2000°C to 100°C200°C.

Aug 12, 2014· 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.
