Cement manufacturing raw materials If you happen to be a geologist, the raw materials quarry is probably the most interesting part of a cement works, maybe unless you view the clinkering process as igneous rocks in the making The most common raw rock 63 Structure of the Industry 64 Production 65 Consumption 66 Trade 67 Issues 7: Further reading MINERAL PROFILE: CEMENT RAW MATERIALS Contents BRITISH GEOLOGICAL SURVEY 11 Definition and mineralogy Cement is a manufactured product made by blending different raw materials and firing them at a high temperature in order to achieve precise chemical proportions of lime, silica, CEMENT RAW MATERIALS International Cement ReviewThere are a number of materials that can substitute for the natural resources that supply both the minerals and/or energy required for clinker and cement production These alternative fuels and raw materials are typically byproducts of other industrial processes or waste materials Alternative Fuels Raw Materials – Cement
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 180250 kg of coal and about 15 tonne of limestone is required to produce a tonne of cementThere are a number of materials that can substitute for the natural resources that supply both the minerals and/or energy required for clinker and cement production These alternative fuels and raw materials are typically byproducts of other industrial Alternative Fuels Raw Materials – CementRaw materials for the production of cement Minerals of natural origin as well as industrial products can be used for the production of cement Starting material for this purpose are mineral compounds containing the main components of cement: lime, silica, alumina RAW MATERIALS FOR CEMENT MANUFACTURING

Raw materials are extracted mainly onsite, which avoids transportation costs and environmental damage Environment cement uses carefully selected wastes from other industries such as secondary raw materials or alternative fuels This helps decrease the environmental impact of other industriesOne of the most important ways of reducing CO2 emissions in cement manufacturing is the use of alternative raw materials that are produced as waste in other industries A very large share of these alternative raw materials comes from the metalworking industry Moreover, coalfired power plants supply ash as well as synthetic gypsumAlternative Raw Materials and Fuels HeidelbergCement25/9/2014 Thirty years ago, cement companies started to treat waste as a source of raw material and energy Today, the cement industry provides a significant contribution to the waste management practices of many countriesWaste management solutions by the cement industry
