Abstract
Geopolymer concrete is gathering on which research attention owing to its quintessential properties fire resistance, drying shrinkage, acid resistance are, mechanical and stinted heat of hydration. In comparison to conventional cement and other materials. In general it is being utilized as an alternative Portland cement concrete. Geopolymer is highly alkalized by sodium silicate and sodium hydroxide, and replaced by 40% of fly-ash and 60% ground granulated blast furnace slag. Present work transpires on investigating the mechanical properties of aforementioned concrete specimens with two concentrated fibers i.e. sisal and coir with varying percentages of 0%,0.5%,1%,1.5%. Mechanical properties such as compressive strength, spilt tensile strength and flexural strength are accentuated in this work. The results suggest that annexation of natural fibers leverages the mechanical properties of geopolymer composites. The findings of this work have serious implications that have proportional applications in construction buildings.
