Cement industries typically produce portland cement, although they also produce masonry cement (which is also manufactured at portland cement plants). Portland cement is a fine,typically gray powder comprised of dicalcium silicate, tricalcium silicate, tricalcium aluminate,and tetracalcium aluminoferrite, with the addition of forms of calcium sulfate.  Raw Material Acquisition Most of the raw materials used are extracted from the earth through mining and quarrying and can be divided into the following groups: lime (calcareous), silica (siliceous), alumina (argilla- ceous), and iron (ferriferous).  Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation.  The plant must minimize the transporta- tion cost since one third of the limestone is converted to CO2 during the pyroprocessing and is subsequently lost.  Quarry operations consist of drilling, blasting, excavating, handling, loading,hauling, crushing, screening, stockpiling, and storing.
