        abstract = {Fly ash (FA) and ground granulated blast furnace (GGBS)-based geopolymer concrete (GPC) are growing in popularity as green construction materials. Studies demonstrated that GPC is brittle in nature; however, this drawback could be mitigated by fiber reinforcement. Environmental factors are more easily accessible if locally available sources are used. The purpose of this research is to investigate the impact of fiber integration in GPC. Jute fiber (JF) and coir fiber (CF) were added to the matrix at a rate of 1% total binder. The samples were examined at molarities of 12 and a sodium hydroxide (SH) to sodium silicate (SS) ratio of 2.5. The specimens were molded and allowed to cure in the ambient environment. The results demonstrated that jute fiber reinforcement had a significant impact on the workability, compressive strength, fracture strengths, water absorption, and microstructure parameters of the suggested geopolymer concretes. Increasing the fiber length and volume fractions in the geopolymer matrix reduced slump values and workability while increasing compressive strength. At 28 days, the specimen with a fiber length of 20 millimetres and volume fractions of 0.75% showed the lowest slump value and the highest compressive strength. In addition, specimens with fiber volume fractions of 0, 0.25, 0.5, 0.75, 1, 1.25, and 1.5% shown a significant increase in splitting tensile and flexural strength. Increasing the volume of the jute fibers to% resulted in a slight drop in the strength of the geopolymers. The specimens prepared with a length of 20 mm and a volume of 1% achieved the highest enhancement of splitting tensile strength and compressive strength at 28 days.},
