Abstract: This article mainly aims at the study of effect of fly ash (FA) and Ground Granulated Blast Furnace slag (GGBS) on the mechanical properties of Geo Polymer Concrete(GPC) as a replacement for OPC, using Sodium Silicate (Na2SiO3) and Sodium Hydroxide (NaoH) solutions as alkaline activators. The proportions of Fly Ash to GGBS Used are (80:20),(60:40),(40:60),(20:80).Alkaline liquid content to Fly ash ratio taken as 0.36 and fine aggregate to total aggregate ratio is taken as 32 percentage1. The ratio of Sodium Silicate (Na2Sio3) solution to Sodium Hydroxide solution is kept constant as 2.51.There identical specimens for each of variation were cast and tested after 7days and 28days ambient curing. Heat curing for polymerization was not necessary due to the presence of GGBS. The experimental results indicate that the mechanical properties, such as Compressive Strength (fck), Split Tensile Strength (fct) and Modulus of Rupture, increase with increase in the percentage of GGBS.A parameter called Binder Index (Bi) is introduced to quantify the effect of Fly ash, GGBS and Molarity on the Compressive Strength (fck), Split Tensile Strength (fct) and Modulus of Rupture of Geopolymer Concrete at ambient temperature. Effect of GGBS to Fly Ash ratio and Effect of Binder Index2 on Compressive Strength(fck) of GPC,Split Tensile Strength(fct) of GPC and Modulus of Rupture of GPC is calculated.
