        abstract = {Sisal and bamboo fibers are being used extensively as they are eco-friendly when compared to artificial fibers and also have a low environmental impact. The hybridization of these two natural fibers is selected to focus on the low ductility of concrete and boost the flexural strength and tensile strength. Moreover, incorporating natural fibers in place of synthetic or artificial ones enhances the sustainability of concrete.
Concrete specimens were prepared with varying fiber dosages and tested for compressive, split tensile, and flexural strengths, alongside reinforced concrete beams subjected to flexural loading. The findings indicate that the most effective dosage is 1% by weight of cement (0.5% sisal + 0.5% bamboo). At this level, compressive strength remained equivalent to conventional concrete, while split tensile and flexural strengths increased by 12% and 6.4%, respectively. Additionally, reinforced beams demonstrated a 7% improvement in ultimate load capacity, finer crack patterns, and higher ductility. These results suggest the potential of hybrid natural fibers as a sustainable and effective reinforcement alternative in structural applications.
Future studies can focus on optimizing the hybrid fiber proportions by exploring a wider range of dosages and various treatment methods to further enhance durability and mechanical performance. The long-term behavior of hybrid fiber reinforced concrete under varying environmental and loading conditions should also be investigated to assess its service life. Additionally, large-scale structural applications and cost–benefit analysis can be carried out to evaluate the practical feasibility of implementing this material in modern sustainable construction.},
