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 Out Of?
Cement is a binding material that is made out of a mixture of calcined limestone and clay. It is used in the construction industry to make mortar and concrete.
The main difference between mortar and concrete is that mortar is used to bind together bricks or other masonry units, while concrete is used as a structural material to create foundations, walls, beams, and so on.
Cement is manufactured by first crushing and grinding the limestone and clay into a fine powder. This powder is then mixed together in a rotating kiln at a temperature of around 1450 degrees Celsius.
As the mixture rotates in the kiln, it slowly starts to form a substance known as clinker. Once the clinker has formed, it is cooled and ground into a fine powder to create cement.
The main use of cement is in the production of mortar and concrete. Mortar is used to bind together bricks or other masonry units and is made by mixing cement with sand and water.
Concrete is made by mixing cement with sand, water, and aggregate (gravel or stone). It is used as a structural material to create foundations, walls, beams, and so on. Cement is a very versatile material and can be used in a wide variety
