Cement Raw Materials used in Manufacturing of Cement
Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale.

Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180-250 kg of coal and about 1.5 tonne of limestone is required to produce a tonne of cement.
Cement Manufacturing Process: What is Cement made of.
Raw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum, Fuel, and Water (in wet method). 1. Limestones: These are sedimentary, calcium carbonate rocks (CaC0 3 ). Most commonly they contain a small amount of magnesium carbonate also.
Manufacturing of Portland Cement – Process and Materials,
13-04-2020· The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker
