CEMENT RAW MATERIALS CemNet
2013-6-9 The raw materials used in cement manufacture are extracted in large quarries, typically with outputs of up to, or over, 2.5 million tonnes per year. Typically about 1.65 tonnes of limestone (1.5 to 1.8 tonnes) and 0.4 tonnes of clay are quarried for each tonne of cement produced.
Raw materials Understanding Cement
The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone
Raw materials for cement manufacturing
Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8.

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.
