Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the ...
Cement consumption is dependent on the time of year and prevalent weather conditions. Nearly two-thirds of U.S. cement consumption occurs in the six months between May and October. The seasonal nature of the industry can result in large swings in cement and clinker (unfinished raw material) inventories at cement plants over the course of a year.
Cement industry has been always among the largest CO 2 emission sources. Almost 5–7% of global CO 2 emissions are caused by cement plants, while 900 kg CO 2 is emitted to the atmosphere for producing one ton of cement. In this work, global strategies and potentials toward mitigation of CO 2 emissions in cement plant have been discussed and the most promising approaches have been introduced.
