Abstract

The present experimental work deals with the development of fiber reinforced geopolymer concrete in standard grade of (G40) incorporating polypropylene and basalt fibers. Equal proportions of fly ash and Ground Granulated Blast Furnace Slag (GGBS) were used as binders by replacing cement, active alkaline liquids like Sodium Hydroxide (NaOH) of (12M) Molarity concentration, and Sodium Silicate (Na2SiO3). In this experimental work, polypropylene fibers were varied at 0.25%, 0.75%, 1.25%, 1.75% and maximum up to 2.25%; volume of basalt fibers were kept constant at 0.25%. The detailed study was performed to analyze, how fibers effect in the geopolymer concrete specimens; also Standard increase in the Compressive strength, Split tensile strength was noticed and increase in flexural strength was found to be adequate.
