PORTLAND CEMENT
All cement products are composed of specific combinations of calcium, silica, iron and alumina and small amounts of additives to achieve a desired profile of properties (e.g., strength, color). Clinker, the principle intermediate manufactured product within cement production, is typically produced from a combination of ingredients, includingCement clinker - Wikipedia,Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cementRaw materials for cement manufacturing,Minerals of natural origin as well as industrial products/by-products can be used for cement production as long as the main components of cement (Cao, SiO2,Al2O3,Fe2O3)are present in a required proportion on mixing and the impurities or undesirable components like alkalies, sulfur, chlorides, Mgo etc are below the allowable levels to ensure cement quality and operationalCO2 Emissions Profile of the U.S. Cement Industry,Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production.
