Heya Mate!!
The Cement is made by heating limestones ( calcium carbonate) with more materials (such as clays)
☆Manufacture of cement :
Lime or calcium oxide, CaO: from limestone, chalk, shells, shale or calcareous rockSilica, SiO2: from sand, old bottles, clay or argillaceous rockAlumina, Al2O3: from bauxite, recycled aluminum, clayIron, Fe2O3: from from clay, iron ore, scrap iron and fly ashGypsum, CaSO4.2H20: found together with limestone

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
