    Advances in Materials Science and Engineering. Abstract The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement .

  • Raw Material Substitution Cembureau

    The main raw material used in cement production has traditionally been limestone. Limestone is abundantly availe, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.

  • ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT

    ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT PRODUCTION. Cement is a complete mixture of mineral substances that gradually harden when mixed with water. It is the product of the reaction of lime with the oxides of silica alumina and iron. It is used in the construction of industry as a blending material.

  • CEMENT RAW MATERIALS International Cement Review

    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. Large reserves of feedstock, particularly of limestone, are required to provide security of supply and these are
