Cement manufacturing is the process of producing cement, a key ingredient in concrete. The process begins with the extraction of raw materials, primarily limestone and clay, which are crushed and mixed. This mixture is then heated in a kiln at high temperatures to form clinker, a hard substance that is ground into a fine powder. After grinding, the cement may be blended with other materials, such as gypsum, to control setting time. The final product is packaged and distributed for use in construction projects, where it acts as a binding agent in concrete and mortar.
