For the construction of any structure, Concrete is the mostly used material. Concrete usage around the world is second after water(V. M. Malhotra, 2000). The main ingredientto produce concrete is Portland cement. On the other side global warming and environmentalpollution are the biggest menace to the human race on this planet today. The production of cement means the production of pollution because of the emission of CO2 during its production (D.M. J. Sumajouw, 2007). There are two different sources of CO2 emission during cement production. Combustion of fossil fuels to operate the rotary kiln is the largest source and other one isthe chemical process of calcining limestone into lime in the cement kiln also produces CO2. Indiawhich is the second largest cement manufacturer world wise reports almost 150 MT of CO2emissions in 2015(R. M. Andrew, 2017). The cement industry contributes about 5% of totalglobal carbon dioxide emissions. And also, the cement is manufactured by using the raw materials such as lime stone, clay and other minerals. Quarrying of these raw materials also causes environmental degradation. To produce 1 ton of cement, about 1.6 tons of raw materials are re- quired and the time taken to form lime stone is much longer than the rate at which humans use it.But the demand of concrete is increasing day by day for its ease of preparing and fabricating inall sorts of convenient shapes. So to overcome this problem, the concrete to be used should beenvironmental friendly.
