  • Description: The production of synthetic materials emits harmful gases, driving researchers to seek eco-friendly alternatives, leading to increased demand for natural fiber-based composites in various industries. With advantages like cost-effectiveness, renewability, and biodegradability, natural fiber reinforced composites gain popularity in concrete applications. Their use in concrete has gained global acceptance for its smaller carbon footprint, reduced energy consumption, and minimized wastage. This research aims to evaluate the suitability of Eulaliopsis binata (EB) fiber in mortar and concrete applications. Mortar samples were prepared using different proportions of alkaline-treated EB fibers (0%, 0.25%, 0.5%, 0.75%, 1% and 1.25% by total weight of mortar) in a cement-sand-water mixture with a 1:1:0.35 ratio. Additionally, concrete with a mix proportion of 1:2.15:3.13 (cement: fine aggregate: coarse aggregate) and a water-cement ratio of 0.618 was prepared. The flexural strength test was conducted using plain concrete as well as concrete with untreated and epoxy-treated EB fiber bars of varying diameters. The results revealed that EB fiber-reinforced mortar exhibited a notable increase in flexural and splitting tensile strength, with a 10.85% and 6.23% improvement compared to plain mortar at 0.75% EB fiber content, while compressive strength decreased. Similarly, concrete reinforced with untreated and epoxy-coated EB fiber bars of 14 mm diameter demonstrated 12.32% and 13.27% higher flexural strength, respectively, than that of unreinforced concrete. These results highlight the potential for affordable green concrete production, supporting sustainable infrastructure development. The EB fiber usage presents an encouraging pathway for environmentally conscious construction practices with reduced environmental impact. •Eulaliopsis binata (EB) is introduced as new sustainable construction material.•EB can be used in the form of both discrete fiber and reinforcement bars.•It decreased the compressive strength but enhanced flexural and tensile strengths.•The optimum content of EB fiber was 0.75% by weight of cement.•EB has potential to replace steel bar for the band of masonry houses in rural area.
