ABSTRACT
This paper presents the relative results of an experimental investigation on the mechanical properties of Geopolymer concrete (GPC), Geopolymer Concrete Composites (GPCC) containing 30% Fly ash (FA), 70% Ground Granulated Blast Furnace Slag (GGBS). Sodium based alkaline liquid is used as an activator. The study also analyses the impact of steel fibers mechanical properties of GPCC. Steel fibers were added to the mix in the volume fractions of 0.5%, 1% & 1.5% volume of the concrete. From the results it is observed that as the age of concrete increases the mechanical properties of GPCC are found to be improving significantly. Inclusion of steel fibers resulted in improved compressive and flexural strengths at the early ages. However tensile strength is found to be improved significantly at later stages. The durability tests are conducted on the GPC mix which gives maximum strength on percentage addition of steel fibres.
