Abstract
The expansion of worldwide economic development in recent decades has called for a corresponding need and requirement for cement production. As an important component of concrete, the cement worldwide production rate has grown from 0.58 billion tons in 1970 to three billion tones in 2010 and is forecast to peak at 6.1 billion tons in 2050, It is expected to increase to 4 billion tons per year and the main expansion is forecasted in countries such as India and China as well as in areas as the Northern Africa and Middle East.
The combustion of fossil fuels and disintegration of the limestone (CaCCE) in the raw mix is the major and direct source for carbon dioxide emissions in cement manufacturing. Roughly half of the emitted CO2 originates from the fuel and half originates from the decarbonation of the raw material which ensure that carbon dioxide is the major air pollutant from cement industry. One of the essential processes for monitoring the influence of radiation factors on climate for the greenhouse effect in the atmosphere is measuring the CO2 concentration, in order to determine the impact of CO2. And one of the most common assumptions regarding to the climate changes both in the geographical present and in the past is the temperature changes result from alterations in the CO2 content in the atmosphere, subsequently changes of the greenhouse effect. CO2 is the greatest concern because it applies a larger overall warming impact than all these other gases exciting in the atmosphere and due to its long lifetime in the atmosphere. Becoming a significant problem that invites worldwide attention to work to decrease the C02 emissions. Because of cement production is a resources and energy exhaustive industry, it is believed that cement is the second most consumed material worldwide, Cement industry at present demands 9% of industrial energy use and is responsible for 7% of carbon dioxide (CO2) emissions globally. So, it will be environmental worth and helpful for the earth to decrease the CO2 emitted
