3 CEMENT PRODUCTION PROCESS AND ENERGY USE 31 INTRODUCTION Cement is an inorganic non metallic substance with hydraulic binding properties and is used as a bonding agent in building materials It is a fine powder usually gray in color that consists of a mixture of the hydraulic cement minerals to which one or more forms of calcium sulfate haveCement history Throughout history cementing materials have played a vital role and were used widely in the ancient world The Egyptians used calcined gypsum as a cement and the Greeks and Romans used lime made by heating limestone and added sand to make mortar with coarser stones for concrete

Cement manufacture is a production processes that is in fact initiated at the mine where the raw materials such as limestone silica aluminates feric minerals and others are obtained Typical materials used for the provision of calcium carbonate in cement manufacturing are limestone chalks marbles marls and oyster shellThe cement production process for example starts with mining of limestone which is then crushed and ground to powder It is then preheated to save energy before being transferred to the kiln the heart of the process The kiln is then heated to a high temperature of up to degrees to convert the material to a molten form called clinker
