Abstract - The commonly utilized general-purpose cement,
in varying percentages, the toughness and mechanical characteristics of concrete can be notably enhanced, leading to enhanced compressive, flexural and tensile strength. The advancement of composite construction materials using jute fiber holds the potential to increase structural strength and extend the lifespan of structures, offering a sustainable solution with a positive environmental impact.
despite its cost and energy intensity, is a key ingredient in concrete production. Concrete, though brittle, possesses strength, durability, and adaptability, making it moldable into various shapes and sizes. However, it is prone to developing structural cracks even before loading, primarily due to drying shrinkage. To mitigate this, natural fibers such as jute can enhance material properties. A research study explored the mechanical characteristics of jute fiber concrete, demonstrating its sustainability and innovative construction material, combining concrete's strength and durability with the eco-friendliness of jute fibers. Jute fiber was chopped and blended into concrete at varying percentages (0.3%, 0.6%, & 0.9% in M30 concrete mixes), and the resulting specimens showed reduced workability with increased jute fiber content. Nevertheless, the inclusion of jute fiber notably enhanced the compressive, tensile and flexural strength of each concrete mix. This study highlights the potential of jute as an additive to improve concrete's durability and strength.
2. LITERATURE REVIEW Saulo Rocha Ferreira and Marco Pepe Sing et al., This research conducted experiments on natural fibers such as sisal, coconut, and jute to identify their adhesion properties in cement. The study analyzed the different characteristics of these fibers and their impact on bonding with cement. This inquiry offers valuable findings on the potential of these natural fibers to enhance the resilience of concrete and offers guidance for forthcoming research in this field. The results indicated that variables like the roughness of the fiber's surface, its aspect ratio, and its composition significantly influence its adhesion to cement. Specifically, fibers with rough surfaces and longer lengths exhibited stronger adhesion, thereby improving the collective strength of the blend. The study recommends considering these inherent qualities of fibers to optimize cement mixtures.
Key Words: Portland cement, Jute fiber, Durability Compressive strength, Flexural strength and Tensile strength.
1.INTRODUCTION Concrete, an essential construction material, has been widely utilized in buildings since ancient times. Its association with Portland cement and rapid increase in production due to urbanization and industrialization have led to environmental concerns. The significant CO2 emissions from the production of concrete and its environmental impact are urgent concerns that must be addressed to mitigate harm to the environment.
Arpitha M, Yashaswini et al., This research conducted experiments on mechanical characteristics of concrete using coconut coir fibers. Fiber Reinforced Concrete is a materials mix including cement, sand, stones, and fibers like natural, steel, or glass. These fibers make concrete stronger and can be eco-friendly and affordable. This study aimed to enhance concrete strength by utilizing cost-effective, sustainable coconut coir fibers, known for their heat resistance and renewability. They added coconut coir to M30 concrete in different amounts and found that 2% coir gave the best strength, making it stronger than plain concrete. From the experiments conducted in the lab, the study concludes that using 2% incorporation of coconut coir fibers based on the weight of cement yielded the most favorable outcomes. The concrete's compressive strength increased by 22.4% at 7 days, 30.37% at 14 days, and 27.18% for 28 days compared to no coir fibers. Similarly, the split tensile strength improved by 33.47% at 7 days, 34.70% at 14 days, and 30.03% at 28 days. Coir fibers enhanced the
Natural fibers, such as jute, offer a cost-effective, renewable, and biodegradable alternative. With unique characteristics and widespread availability, natural fibers have been employed for diverse applications for thousands of years. Jute is recognized for its robustness, resilience, and ecofriendliness, finding applications in textiles, packaging, home furnishings, and more. Its versatility and sustainability make it an attractive option for diverse industries. Research efforts focusing on incorporating jute fiber into concrete have shown promising results.
