The cement industry is an energy intensive industry with energy typically accounting for 3040% of production costs (ie excluding capital costs) Various fuels can be used to provide the heat required for the process In 1995 the most commonly used fuels were petcoke (39%) andNatural gypsum can be used in concrete production as a replacement for calcium aluminate cement (CAC), opening the possibility of replacing the natural gypsum with FGDG in this application with success, even though some studies have reported a reduction of compressive strength and water solubility when compared to Recent advances in flue gas desulfurization gypsum processes and

Full article: An overview of alternative raw materials used in cement

Raw materials chemistry Cement manufacture requires a source of calcium, such as CaCO 3 or CaMg (CO 3) 2, which comprises almost 80–90% of the total and the rest is iron oxide (Fe 2 O 3, Fe 3 O 4), quartz (SiO 2), and clay/bauxite (Alsilicates) (Aïtcin and Flatt Citation 2015; Hewlett Citation 2003; Peray and Waddell Citation 1986)Traces of Na 2 O, K 2 O, For the great investment and establishment of cement industry, there are essential elements to be considered like; correct infrastructure selection for location of industry (Ozguner et al, 2014), sufficient reserves of raw materials and a typical sampling of the raw materials used to make Cement (Shah et al, 2007), correct calculations for the feasible Determination Of Limestone Quality In Cement Production
