Abstract

Geopolymer concrete (GPC) are representing the most promising green and eco-friendly alternative to Ordinary Portland cement (OPC). This paper presents results of an experimental program on the mechanical properties of Fibre Reinforced Geopolymer Concrete (FRGPC) such as compressive strength, split tensile strength, flexural strength. FRGPC contains flyash, alkaline liquids, fine aggregate, coarse aggregate and steel fibre. Alkaline liquid to fly ash ratio was fixed as 0.45 with 100% replacement of OPC. For alkaline liquid combination, ratio of sodium silicate to sodium hydroxide solution was fixed as 2.5. Steel fibre was added to the mix in volume fractions of 0.5%, 1.0%, and 1.5% by volume of concrete. Specimens were subjected to 24 hours of Heat curing at 80°C in heat curing chamber. Based on the test results, optimum % were formulated and compared it with conventional Concrete.
