Raw Material Extraction. Cement uses raw materials that cover calcium, iron and aluminum. Such raw materials are limestone, shale and sand. Limestone is for calcium. It is combined with much smaller proportions of dolerite, sand, and aluminium. Sand clay fulfil the need of silicon, iron and aluminum. Generally cement plants are fixed where the quarry of limestone is near bye.
