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. These ingredients, when heated at high

The cement manufacturing process requires the use of raw materials such as limestone and additives to control the alumina, silica and iron content. In addition, a relatively high amount of energy is needed to convert the limestone to calcium-oxide and to solidify and compress the material at 1,450°C.
