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

:Concrete and CementCement Price DataConcrete Commodity Price · The Cement Manufacturing Process. The production of cement involves a series of steps that transform raw materials into the final product. The process begins with the crushing and grinding of raw materials, followed by the formation of clinker, and concludes with the grinding and mixing of clinker to produce cement.
