Understanding The Structural Behaviour of Biocomposites Through Experimental Method

– This study presents an experimental investigation on the performance of banana fiber reinforced concrete (BFRC) using M40 grade concrete. Banana fibers, obtained from agricultural waste, were incorporated in varying proportions to evaluate their influence on compressive strength and structural behavior of concrete. Concrete specimens were prepared in accordance with IS 10262:2009 guidelines and tested at curing ages of 7, 14, and 28 days. The results indicate that the inclusion of banana fibers enhances the mechanical properties of concrete by improving crack resistance, ductility, and overall load-carrying behavior. The 28-day compressive strength reached 44.04 MPa, exceeding the characteristic strength requirement of M40 grade concrete. It was observed that an optimal fiber content of approximately 1% provides the best performance, whereas higher fiber content leads to reduced workability and strength due to poor dispersion. The findings highlight the effectiveness of banana fibers as a natural micro-reinforcement material. In addition to mechanical improvements, the use of banana fibers promotes sustainability by utilizing renewable resources and reducing dependence on synthetic materials. This study demonstrates the potential of BFRC as a cost-effective and eco-friendly alternative for modern construction applications.
