| dc.description.abstract | This study examines the incorporation of recycled and renewable fibers—such as steel,
plastic, glass, and coconut fibers—into concrete to enhance its mechanical properties and
improve sustainability. The research focuses on the effects of these fibers on the compressive
strength of fiber-reinforced concrete (FRC) at various curing periods (3, 7, 14, and 28 days).
Results show that glass fibers significantly improve compressive strength, with a peak of
21.81 MPa at 28 days, followed by steel fibers and coconut fibers, which also contributed to
strength gains, particularly at higher fiber contents. Plastic fibers, while enhancing the
concrete's toughness, showed more moderate improvements. The study also highlights the
environmental sustainability of using recycled fibers, particularly coconut and plastic fibers,
as an eco-friendly alternative to synthetic materials. The findings suggest that the use of these
fibers could lead to more durable, cost-effective, and environmentally sustainable concrete.
However, further research is needed to explore long-term durability, economic feasibility,
and the environmental impact of fiber-reinforced concrete under varying conditions. The
study also recommends future research into hybrid fiber systems and life-cycle assessments
(LCA) for a deeper understanding of the material's sustainability and performance. | en_US |
