EXPERIMENTAL INVESTIGATION ON EFFECT OF INCLUSION OF HOOKED STEEL FIBER ON GGBS BASED GEOPOLYMER CONCRETE

This paper presents the result of an experimental investigation on the mechanical properties of geopolymer composites containing Ground Granulated Blast Furnace Slag (GGBS), alkaline liquids and steel fibers. This study analyses the impact of steel fiber on mechanical properties such as compressive strength, split tensile strength, and flexural strength of hardened Geopolymer Concrete (GPC). The mixture was prepared with alkaline to GGBS ratio as 0.4. Steel fibers were added to the GPC in volume fractions of 0.25%, 0.5%, 0.75%, and 1% volume of concrete. Specimens were subjected to 8 hours of oven curing at 72⁰C. Based on the test results the optimum percentage of steel were formulated.
