Raw Materials Used in Cement Industry CMA India

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.

Alkalies : The most of the alkalies present in raw materials are carried away by the flue gases during heating and the cement contains only a small amount of alkalies. If they are in excess in cement, they cause a number of troubles such as alkali-aggregate reaction, efflorescence and staining when used in concrete, the brickwork of masonry mortar.
