Fly ash (FA) utilization in concrete as partial replacement of cement is gaining importance day by day. Technological improvements in thermal power plant operations as well as collection systems of FA improved the quality of FA. FA is a waste product from the combustion of pulverized coal in electricity power plants and considered as a contributing factor for air, water and soil pollution that lead to human health problems and various geo-environmental issue. The use of FA in cement can reduce the consumption of natural resources and also diminishes the effect of pollutant in environment. In the current economic conditions, all construction works required cost efficient with good quality of work. Therefore, to increase the effective utilization of FA, Lime Sludge (LS) an industrial waste, is used in the current study for the production of green cement. The utilization of FA varying (5, 15, 25 and 35%) plus 15% LS in terms of physical properties of cement with Portland Pozzolana Cement (PPC) containing FA varying (20, 30, 40 and 50%) have been evaluated. The outcome from this study would help to utilize up to 50% FA plus LS with acceptable compressive strength vis a vis saving of limestone (CaCO3) and reduction in carbon dioxide (CO2) emissions.
