Cement is primarily made from a mixture of limestone and clay or shale. These raw materials are heated in a kiln to form clinker, which is then ground into a fine powder and mixed with gypsum to control setting time. Additional materials, such as fly ash or slag, may also be added to enhance certain properties of the cement. The resulting product is a key ingredient in concrete and mortar used in construction.
