Geopolymer concrete(GPC) is an innovative construction material, which utilize fly ash as a base material
and alkaline solution as an activator. However conventional GPC recipe requires temperature curing which can be
eliminated by introducing Ground granulated blast-furnace slag as a base material. This experimental investigation
focuses on utilization of Ground Granulated Blast Furnace Slag (GGBFS) as a primary base material. It is observed that
utilization of GGBFS in GPC develops minor surface cracks due to early setting of concrete, which can be eliminate by
introducing Fly ash (FA) and Silica Fume (SF) as a binding material, which resulted in less surface cracking and even
hardened mass. This paper represents strength aspect of GPC prepared with ternary blending system. Strength
properties of GPC evaluated by performing Compressive strength test, Splitting Tensile strength test, Flexural strength
test and dropping weight impact resistance test.
