In the case when the composition of the basic raw material differs from these values, various mineral additions are used. Clay raw materials reduce the CaCO 3 content and increase the content of SiO 2, Al 2 O 3 and Fe 2 O 3. According to the classification used in a cement industry, clay raw materials are qualified to the law raw materials group.
One viable method is Supplementary Cementitious Materials SCMs. SCMs are commonly industry by-products or raw materials, such as Slag, limestone, Fly ash, silica fume, natural pozzolan. Whether binary blended or even ternary blended, SCMs can replace part of cement without sacrificing equivalent engineering properties.
limestone sorbent as a raw material for making cement can have a very favorable effect not only on the economics of the CaL-FB process, but also on the cement manufacture in terms of i reduced generation of carbon dioxide and pollutants, ii saving of raw materials and fuel, iii decreased flow rate of gaseous emissions.
It is the main raw material required for production of cement. About 1.5 tonnes of limestone is used in the manufacture of 1 tonne of cement. Cement grade limestone is located only in certain areas in the country leading to establishment of cement plants in clusters.
