  • Cement Raw Materials used in Manufacturing of Cement

    07.06.2016· Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale. Let’s understand the various types of cement raw materials

  • 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

  • Uses of alternative fuels and raw materials in the cement

    01.07.2013· Although MBM has been considered as an alternative fuel in the cement industry, its use as raw material has not. Actually, there are very few references concerning this topic in literature. In spite of the lack of environmental analysis of the use of MBM as a raw material, Colling conducted one of the first studies concerning the feasibility of producing concrete products from MBM ash. After

  • Alternative Raw Materials and Fuels HeidelbergCement

    That is why we make greater use of waste materials and by-products from other industries as valuable raw materials and fuels. We use alternative raw materials for the production of clinker, which is the most important intermediate product in the manufacture of cement. In this way we reduce the amount of CO 2 intensive clinker in the final product. The increased use of alternative raw materials

  • How Cement Is Made Portland Cement Association

    Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.
