What Is Cement Made From?

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

What Is Cement Made From?

Cement is a binding agent and is a key ingredient in the production of concrete. It is made by heating limestone with clay in a kiln and then grinding the resulting mixture to a fine powder.

The main raw material for the production of cement is limestone. The limestone is first crushed and then transported to the factory where it is stored and homogenized.

The homogenized limestone is then fed to the kiln where it is calcined at a temperature of around 1450°C. The calcined limestone is then ground to a fine powder in a grinding mill and the resulting product is cement.

Cement is used in the construction industry to make concrete, mortar and grout. Concrete is the most widely used construction material in the world and is made by mixing cement with sand, gravel and water.

Mortar is used to bind bricks and stones in the construction of buildings and grout is used to fill the gaps between tiles.

Cement is a fine powder which, when mixed with water, forms a paste that sets and hardens to bind other materials together. The word ‘cement’ comes from the Latin word ‘caementum’, which means ‘stone’.
