A Study On Compressive Strength Attributes Of Jute Fiber Reinforced Cement Concrete Composites And Comparing Then With Ordinary Concrete

Abstract

A proportionate combination of water, aggregate (gravel or sand), cement, and admixtures to impart desirable qualities make up concrete. Concrete has great compressive strength but is also brittle; its tensile strength is just 10% of its compressive strength, and it cracks easily, limiting how it may be used. One way around these restrictions is to use fiber-reinforced concrete, made of concrete mixed with fibrous material. Fiber-reinforced concrete (FRC) has become a novel and environmentally friendly material for various uses, such as runways, large industrial building floors, and building pavements. This study investigates using non-metallic fibers, such as jute fiber, in concrete. Natural fibers are employed in modern technologies. This article compares standard plain concrete specimens to study the strength qualities of non-metallic fibers in concrete. The fiber content of concrete increases when Jutes fiber is added, and the compressive strength rises to a particular point. Chops jute fibers were used in this work to determine whether the 28-days strength might be increased to make an FRC material. High fiber concentrations led to fiber clumping, which caused problems with casting and mixing. Concrete is mixed with 10- and 15-mm long jute samples (0.1% and 0.2%) of volumetric weight in this experiment. The mix design complied with the guidelines provided by the American Concrete Institute (ACI). The proportions of cement to water were 0.45 and 0.55. Poor workability is another effect of the concrete's declining compressive strength. The 28-day compressive strength was 64.34% higher than that of regular concrete, and 0.1% was found to be the ideal jute content. The fiber's length impacted both its compressive and tensile strengths. As the fiber content rises, the FRC's ductile behavior gets better. Additionally, the analysis revealed that FRC's modulus of elasticity was higher than regular concrete.
