Performance of Jute Fiber Reinforced Concrete in the Context of Bangladesh

Concrete is a mixture made up of a proportional mixture of water, aggregate (sand or gravel), cement, and admixtures to impart advantageous properties. Despite its high compressive strength, concrete is fragile; compared to its compressive strength, its tensile strength is only about 10%, and it also has a low resistance to cracking, which restricts its application. Fiber-reinforced concrete, which combines concrete with fibrous material to solve these limitations, is a solution. Fiber-reinforced concrete (FRC) has emerged as a new sustainable material for a varied range of applications, including building pavements, huge industrial building floors, and runways. Natural fibers are used in contemporary technologies (jute fiber) and this study explores the use of non-metallic fibers (jute fiber) in concrete. The purpose of this article is to analyze the strength properties of non-metallic fibers in concrete and compare them to standard plain concrete specimens. When Jutes fiber is added to concrete, the compressive strength increases to a certain limit, increasing fiber content. In this study, chopped jute fibers were utilized to create an FRC material to see whether the 28-day strength could be improved. Mixing and casting issues were created by fiber clumping at high fiber concentrations. In this experiment, 10 mm and 15 mm long jute samples (0.1%, 0.2%, and 0.3%) of volumetric weight are mixed with concrete. The mix design followed the American Concrete Institute's recommendations (ACI, 211.1-91). The ratio of water to cement was 0.4. Compressive strength of the concrete decreases, also resulting in poor workability. When compared to ordinary concrete, the compressive strength of 28 days was improved by 64.34%, and the optimal content of jute was determined to be 0.1%. The compressive and tensile strength of the fiber was also affected by its length. The ductile behavior of the FRC improves as the fiber content increases. In this investigation, it was also discovered that the modulus of elasticity of FRC was increased when compared to ordinary concrete
