Investigation on the effect of steel fibers in geopolymer concrete

Abstract

This research work throws lime light in mitigating the brittleness of GGBS based geopolymer concrete through the addition of high modulus fibers. This work invests the effects of incorporation of steel fibers in geopolymer concrete over workability, compressive, split tensile, flexural, ductility factor and energy absorption capacity. The steel fibers were added in proportions such as 0.25, 0.5, 0.75, 1 and 1.25 percent of the volume of concrete. The results report that addition of steel fibers have positive impacts over mechanical properties, ductility and energy absorption capacity. This paves way for extending the scope of geopolymer concrete in various facets to replace the cement concrete effectively.
