  • What is Cement Clinker? Composition, Types & Uses Civil

    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.

  • Portland Cement Clinker an overview | ScienceDirect Topics

    Portland cement clinker is produced in a kiln from calcareous and siliceous raw materials and the primary cement clinker minerals are formed in a solid state at high temperature (c. 1450°C) using a liquid flux to transport the reactants. A description of the process is given in Chapter 2. The material which is produced through this process was first called Portland cement because of its

    The raw material preparation stage of cement manufacture results in the production of a rawmix that is in a suitable state for feeding to the kiln in which it is converted by heat into clinker. This is a chemical transformation. The rawmix consists of a mixture of materials that will react together to form the calcium silicates that confer on the clinker its strength-giving properties. The

  • Raw materials Cement

    Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

Cement is therefore essentially a mixture of calcium silicates and smaller amounts of calcium aluminates that react with water and cause the cement to set. The requirement for calcium is met by using high calcium limestone (or its equivalent calcareous raw material) and clay, mudstone or shale as the source of most of the silica and alumina.
