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 Clayis hydrated aluminium silicate and iron (iii) oxide having chemical formula Al 2 O 3 SiO 2 Fe 2 O 3.2H 2 O.

See DetailsOf the all, thesilicates C 3S and C 2 S are the most important compounds, which are responsible for the strength of hydrated cement paste. The presence of C 3 A in cement is undesirable.C 4 AFis also present in cement in small quantities and compared with other three compounds, it does not affect the behavior significantly.
