Types of cement clinkers and their applications

A lot goes into the production of cement and various processes are also involved. One such stage involved in the production of cement is called kilning. This is the stage where cement clinker is produced. Clinkers are used to bind various cement products. The clinkers usually appear as lumps or nodules when homogenous raw materials are mixed and processed during cement production. 

Cement clinker is grey and comes to form when limestone and clay are heated to the point of liquefaction in the cement manufacturing units. 

Cement clinker is often stored by cement manufacturers so that it can also be used when the raw materials to produce cement are scarcely available.

The best feature of cement clinker is that it can be stored in its best form for long periods without any sign of quality loss. Sometimes cement manufacturers use the stored clinkers to produce the excess requirements of cement. 

Reliable cement manufacturers like Wonder Cement follow a guideline procedure when it comes to cement clinkers.

Just like cement, there are various types of cement clinkers too that are used for specific purposes. 

Let’s look at the types of cement clinkers and their uses. The classification of clinkers simply depends on the kind of cement they are produced for!

1. Sulfate Resistant Clinker

Sulfate-Resistant Clinker is used to produce sulfate-resistant cement wherein a low percentage of gypsum is also added. This material is used within the concrete structure and is further used to carry out construction work in sulfate-rich areas. Some of the construction sites that need sulfate-resistant clinker are underground structures, sewage plants, and so on. 

2. Low Heat Clinker

This cement clinker has low heat properties and is hardly produced these days. This is simply because the cement produced from low-heat clinker has extremely low-heat properties. This kind of cement is usually used for the mass construction of structures like dams. 

3. White Clinker

Just like the name suggests, white clinker produces white cement. This is generally used for building aesthetic elements in structures. In some cases, white cement is also mixed with different colour pigments to meet architectural design requirements.

4. Low-Alkali Clinker

Low-Alkali clinker is used to produce low-alkali cement. This kind of cement is used for structures that have to be moisture-resistant. The structures usually include runways, airports, etc. 

5. Belite Calcium sulfoaluminate Ternesite (BCT)

This is used to produce clinkers that have up to 30% less carbon dioxide emissions. This procedure is energy efficient which, in turn, lessens the electricity charges.
