The concrete, thus, as a modern-day building material, sustains serious challenges in the area of environmental and mechanical limitations. This investigation concentrates on the viability of jute fiber as a sustainable reinforcement stuff. For jute fiber-reinforced concrete (JFRC) composites, a complex explorative sequence was developed to examine mechanical characteristics such as split tensile strength, compressive strength, flexural strength, modulus of elasticity, and durability tests, for example, water absorption, chloride penetration resistance, water permeability, and thermal conductivity. The investigation went further to evaluate the embodied carbon of JFRC in order to appraise its environmental sustainability. Results show that adding jute fiber by a volume fraction of between 0.25 and 0.5% makes noticeable enhancements to mechanical characteristics. On the other hand, a larger fiber content (>0.5%) and longer fibers (17.5 mm) were also found to increase porosity and water absorption, adversely affecting durability. The study brings out the identification of optimum fiber length (12.5 mm) and content dictating mechanical action against durability. Jute fiber integration substantially reduces concrete's embodied carbon, making it an eco-friendly building alternative. This research generates an important understanding of natural fibers within concrete, opening a route to developing low-carbon, high-performance building materials.
