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.
