Abstract

The experimental program consisted of determination of the Split Tensile Strength (fct) of the Combined fiber Reinforced Geopolymer Concrete (CFRGPC) by casting and testing cylinders of size 100 mm wide 200 mm long. Two different Ground Granulated Blast Furnace Slag (GGBS) to Fly Ash (FA) ratios (60:40, 40:60) are used. Three different Molarities 8, 10 and 12 are used. For making CFRGPC, combined fiber combinations R0S10, R2S8, R4S6, 6S4, R8S2 and R10S0 are used. Three identical specimens for each variation were cast and tested for 7 days and 28 days ambient curing. Two Parameters called ‘Binder Index and Modified Binder Index’ are introduced to quantify the effects of molarity, GGBS, fly ash and fiber effect on split Tensile Strength of CFRGPC is presented.
