The chemical formula of cement is CaO.Al 2 O 3.Fe 2 O 3. Raw Material Required for Manufacturing of Cement The two important raw materials used for the preparation of cement are: 1. Limestone. The chemical formula of limestone is CaCO 3 and it is used in the manufacture of cement just to provide CaO. 2. Clay
Cement is a hydraulic binder used in conjunction with other materials whose performance can only inferred and predicted during its manufacture. As a consequence there is an overriding requirement to minimise variability in material composition and processing throughout the manufacturing process.
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 temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.
