What Is Cement Made Of?
Common raw materials used to make the powder 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 temperatures form a rock-like substance called clinker that is ground into the fine powder that we call cement.
