How Is Cement Made?

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.

How Is Cement Made?

Cement is one of the most common construction materials used around the world. It is a finely ground, usually gray powder that is used in the production of concrete, mortar, and other building materials. Cement is made from a mixture of calcium, silicon, iron, and other ingredients. The exact composition of cement varies, depending on the type of cement used. In general, however, cement is made by combining limestone and clay or shale, and then grinding them into a powder.

The first step in making cement is to mix the ingredients together. Limestone and clay or shale are ground to a fine powder in a grinding mill and then mixed together in a rotating mixer. The resulting mixture, called raw meal, is then transferred to a kiln for further processing. In the kiln, the raw meal is heated and turned into clinker, which is a small, hard nodule of cement. The clinker is then cooled and ground into a fine powder, which is known as Portland cement.

Once the cement is made, it is ready to be used in the construction of buildings, roads, and other structures. Cement can be used in either dry or wet form. In dry form, cement is mixed with sand, water, and
