2. Cement Manufacturing Process: The main component of cement is clinker, which is produced from raw materials, such as limestone and clay. [8]. Limestone supplies CaCO 3 for the cement production. Silica, alumina, and iron are considered to be other raw materials. The lime stone used for cement manufacturing contains 75-90 % of CaCo 3
