Abstract – Cement a byproduct of the natural resources is at a high requirement, which is both economically and environmentally backward. Taking up this issue and considering various supplementary materials, of which flyash and GGBS(Ground Granulated Blast Furnace Slag) on combination provides much better results. Flyash is a common supplementary pozzolanic material, which is a byproduct from Thermal Power Plants. It enhances the mechanical properties of mortar without altering the conventional properties. GGBS , which is also a supplementary pozzolanic material, admixture and a byproduct from production of Iron and steel-making. It enhances the mechanical properties, increases cohesion and reduces bleeding and permeability. Geopolymer mortar is an innovative and green sense composite material for construction, which is obtained by chemical action of inorganic molecules. This composite material does not utilize ordinary Portland cement where in place flyash and GGBS is used in a blended form. Geopolymer is a low carbon dioxide cementitious material when compared to ordinary Portland cement, as it does not depend on calcination process of limestone that produces carbon dioxide. The binder used in geopolymer is sodium based alkaline activators. Studies were carried on various combination with GGBS blending on 25 percentage – 75 percentage. Engineering properties were evaluated and the optimum replacement was determined. Thus the results are evaluated and analyzed.
