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.

What are Cement Clinkers?

Cement clinker uses limestone, clay, and iron as the main raw materials. It is prepared into a raw material at an appropriate ratio, and is partially or completely melted and cooled to obtain a semi-finished product. In the cement industry, the main chemical components of Portland cement clinker are calcium oxide, silica, and a small amount of alumina and iron oxide. The main mineral ...

What are Cement Clinkers? (with pictures)

Cement clinkers are made from bauxite. The most commonly used cement in the world is Portland cement, which is formed at high temperatures that chemically combine the ingredients into new components, including calcium silicates and calcium aluminates. When the cement clinkers are ground with approximately 5% gypsum, they form Portland cement.

Portland cement clinker is rendered by heating at high temperatures a homogeneous combination of raw materials in a revolving kiln. The chemical reaction components average about 1,450 ° C (2,640 ° F) at their sintering point. Aluminum oxide and iron oxide are present only as a flux to reduce the sintering temperature and contribute little to the cement strength. It is necessary to limit the ...

The materials are then fed through a kiln at 2,600º F to produce grayish-black pellets known as clinker. The alumina and iron act as fluxing agents which lower the melting point of silica from 3,000 to 2600º F. After this stage, the clinker is cooled, pulverized and gypsum added to regulate setting time. It is then ground extremely fine to produce cement.
