What is Cement Clinker? Composition, Types Uses

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 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln. ...

 · CO 2 emissions are directly proportionate to the amount of clinker used in cement production. Therefore, clinker can be substituted by cementitious materials such as natural and calcined pozzolans, as well as industrial byproducts such as fly ash and blast furnace slag. Similarly, the use of pozzolans depends on their availability, as natural reserves are limited to specific regions. .
