  • CEMENT RAW MATERIALS International Cement Review

    The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The levelRaw Materials of Cement Expert Civil,Sep 07, 2018· 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.

    Portland cement is one of the basic materials in the construction industry. The principal component of Portland cement is clinker. According to the cement nomenclature, clinker contains two silicate phases: Ca 3 SiO 5 (alite) and Ca 2 SiO 4 (belite), as well as aluminate and ferrite. The alite to belite ratio is responsible for the strength of Portland cement in cement clinker.LafargeHolcim, industry experts in building materials,LafargeHolcim is the global leader in building materials and solutions and active in four business segments: Cement, Aggregates, Ready-Mix Concrete and Solutions & Products. Following our pledge to net zero, our ambition is to lead the industry in reducing carbon emissions and shifting towards low-carbon construction.

    The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants. An excess amount of magnesia may make the cement unsound and expansive, but a little amount of it can add strength to the cement. Production of MgO-based cement also causes less CO2 emission. All cement is limited to a content of 6% MgO.RAW MATERIALS FOR CEMENT MANUFACTURING ,Raw materials for the production of cement Minerals of natural origin as well as industrial products can be used for the production of cement.
