  • Cement Productionan overview ScienceDirect Topics

    The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5 of total anthropogenic emissions (IFC 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure 2009).

    The 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 1480 degrees to convert the material to a molten form called clinker.
