Enhancing the performance of ECC through chemically treated Jute fibre reinforcement

Abstract

In this comprehensive study, the potential of chemically treated jute fibres as a reinforcement in Engineered Cementitious Composite (ECC) is thoroughly investigated. The alkali treatment process significantly enhances the interaction between these fibres and the cement matrix, resulting in substantial improvements in the mechanical properties of the concrete. Various parameters, such as direct tensile strength of the fibre, compressive strength, flexural strength, direct tensile strength of ECC, modulus of rupture, modulus of elasticity, bond strength between ECC and concrete, and bond strength between ECC and steel, are meticulously evaluated for both treated and untreated jute fibres integrated into the concrete. The research underscores the critical importance of maintaining an optimal fibre content, typically around 1.5%, to achieve a well-balanced mix design that ensures optimal composite performance. The study places strong emphasis on the adoption of sustainable and eco-friendly construction practices by incorporating biodegradable materials. Furthermore, it highlights the pivotal roles played by aspect ratio and interfacial bonding in influencing the stiffness, strength, and overall durability of the concrete. Ultimately, this research contributes valuable insights that advance the field of composite materials and encourage the adoption of sustainable construction approaches.
