It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement.
Cement is a mixture of clay and limestone. Both are heated to very high temperatures and then ground into a fine powder. The heating process is essential to activate the chemical binding action and hydration processes found in cement. If you were simply to grind up hardened clay and limestone, you would not get the same results.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement. Why cement is called portland cement?
The most important raw materials for making cement are limestone, clay, and marl. These are extracted from quarries by blasting or by ripping using heavy machinery. Extracting raw material II: crushing and transportation Wheel loaders and dumper trucks transport the raw material to the crushing installations.

Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materials: Lime or calcium oxide, CaO: from limestone, chalk, shells, shale or calcareous rock Silica, SiO 2: from sand, old bottles, clay or argillaceous rock Alumina, Al 2 O 3: from bauxite, recycled aluminum, clay
Concrete is made from a mixture of paste and aggregates with the paste being water and Portland cement and the aggregates being gravel, sand, and crushed stone. If …
By its turn, Portland cement, which is by far the most common type of cement in use, is manufactured basically from limestone and clay (or marl) with lower amounts of gypsum.

Cement is a fine powder made by heating limestone and clay minerals to very high temperatures. The resulting material, called clinker, is then ground with a pozzolan such as silica fume or fly ash into the powdered product we call cement. Cement and water form a paste through which almost no particle can pass.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminium, 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.

Concrete is made from a mixture of paste and aggregates with the paste being water and Portland cement and the aggregates being gravel, sand, and crushed stone. If you are one of those who use cement and concrete interchangeably, don't feel bad because it has been a common occurrence for 600 years! Cement production illustrated 1.)
