Abstract
To meet the requirements of globalization, in the construction of buildings and other structures concrete plays the major rightful role and a large quantum of concrete is being utilized. The constituent materials of concrete include cement, sand, coarse aggregate and water. For better performance and to meet the requirements additives or sometimes super plasticizers are used. Portland cement clinker production consumes large a mounts of energy (850 kcal per kg of clinker) and has a considerable environmental impact. This involves massive quarrying for raw materials (limestone, clay, etc.), as it takes 1.7 tones to produce 1 ton of clinker, as well as the emission of greenhouse and other gases (NO x , SO 2 , CO 2 ) into the atmosphere. Around 850 kg of CO 2 are emitted per ton of clinker produced.
