ton of CO2/ton of clinker. The second source is from the combustion of fossil fuels amounting to about ton of CO2/ton of clinker. Therefore, nearly a ton of CO2 is produced for each ton of cement. Over 7 percent of the total humanproduced CO2 is from the production of cement, and the potential for cement replacement with fly ash is a big step in the direction of reducing greenhouse gas ...

Clinker are intermediate products and main constituent of most cement are the key component of any cement, providing the necessary hydraulic properties to cements. They are industrial products, produced from rotary kilns, resulting from the heating (up to temperatures of 1450 C) and successive cooling of raw materials (mostly limestone).
