In the present study, it is aimed to use fly ash and GGBS as full replacement to cement. They contain high amount of silica and alumina , which can be activated with the help of alkaline solution(i.e.,NaoH & Na2Sio3) to produce geo-polymer concrete(GPC). In the present work investigations are carried out to find strength properties of fly ash and GGBS based geo-polymer concrete i.e. (G 40) with the addition of glass fiber by using various combinations of fly ash(FA) and GGBS(i.e FA 100%+ GGB 0% , FA 80% + GGBS 20% , FA 60% + GGBS 40% ) with constant molarities (i.e.8M), including addition of glass fiber in various percentages (0.5%, 1.00%, & 1.5%).The specimens prepared with above specification are cured in ambient conditions. Specimens are tested for compressive strength and splitting tensile strength at various ages (i.e 7 days,28 days,56 days) in order to find out effective combination of fly ash and GGBS based geo-polymer concrete mix with optimum dosage of glass fiber which can give desired strength properties.
