How is cement made?

Description cement – cement is normally produced using limestone, which is mixed with clay and other components to create modern commercial cement designed for construction applications.

Limestone is heated to produce lime, and mixed with clay and water to produce a paste which is then kiln-treated to form a clinker. The clinker is finely ground and combined with gypsum to create cement. Water is then added to the mix to form a paste binding additional materials together.

Cement binds other materials to it

Cement is a binding agent which is very rarely used on its own. It is commonly used to make concrete, a combination of cement, sand, gravel and water.

In its role as a binder, the cement hardens and sets, adhering successfully to other materials such as aggregates to create tough and robust products used primarily in the construction industry.
