Although the cement industry used only one-quarter of one percent of total U.S. energy, it is the most energy-intensive of all manufacturing industries, with a share of national energy use roughly 10 times its share of the nation's gross output
3 CEMENT PRODUCTION PROCESS AND ENERGY USE 3.1 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 have
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
Nov 21, 2011· In other words, shipping cement costs more than the profit from selling it.Opportunities:The cement industries have opportunities as well. One such opportunity is the cementindustrys efficiency. The cement industry has recently streamlined its production efforts,using dry manufacturing instead of wet, which is heavier and more time-consuming.

The cement sub-sector consumes approximately 12–15% of total industrial energy use. Therefore, a state of art review on the energy use and savings is necessary to identify energy wastage so that necessary measures could be implemented to reduce energy consumption in this sub-sector.
energy saving methods and thermal energy saving methods. The results were presented in the form of energy flow diagrams that made the results easy to understand. Worell et al.

3.1 CO2 Cement Production . Overview of Cement Production Cement is an important construction ingredient around the world, and as a result, cement production is a significant source of global carbon dioxide (CO2 ) emissions, making up approximately 2.4 percent of global CO2 emissions from industrial and energy sources (Marland et al., 1989).
Over recent decades there has been a move away from the wet process to the more energy efficient dry process. In Europe, for example, about 78% of cement production is from dry process kilns, a further 16% of production is accounted for by semi-dry/semi-wet kilns, and only about 6% of European production now comes from wet process kilns.
