Geopolymer Concrete, Copper Slag, Compressive Strength, Split Tensile Strength, Modulus of Elasticity


The present paper mainly focused on mechanical properties of geopolymer concrete (GPC) incorporating copper slag (CS) as fine aggregate. In this study, CS was replaced at different replacement levels (0%, 10%, 20%, 30% and 40%). Fly ash and ground granulated blast furnace slag were used as geopolymer binders. Combination of NaOH and Na2Sio3 solution were used as activating solution. Mechanical properties viz., compressive strength, split tensile strength and modulus of elasticity were found after 7, 28 and 90 days respectively. From the results, it is concluded that the improvement in mechanical properties up to 40% CS replacement was observed.
