Study on Concrete Performance Using Waste Badminton String Fiber As Reinforcement

Abstract

Concrete is the world s most demandable material for the infrastructure newlinedevelopment. But its brittleness and unsustainability drive the researchers to explore newlineinnovative solutions for improving the durability aspect, enhance its mechanical newlineperformance, and reduce environmental impact. newlineTo address these challenges fibers like steel, glass and synthetic can be newlinereinforced, to enhance the mechanical properties, which results in the development of newlineFiber Reinforced Concrete (FRC). However, use of commercial fibers increases the newlinecost of FRC. To overcome this, use of waste fibers could be a sustainable idea and costeffective newlinealternative. newlineThe key idea of this was the use of Waste Badminton String Fiber (WBSF) as a newlinereinforcement in concrete. These badminton strings which cutoff from the racquet newlinesystem after their potential usage they become waste, which cannot be recycled or newlinereused. As per the data of Badminton World Federation, more than 339 million people newlineplay badminton worldwide, which leads a waste of 7000 tons causing an environmental newlineissue. As WBSF was found to have a high tensile strength these fibers can be used in newlineconcrete to increase the structural efficiency. newlineThe physical characteristics of WBSF was examined using Scanning Electron newlineMicroscope (SEM), were the diameter and net cross-sectional area of WBSF was found newlineto be 777 and#956;m and 4,89,909 and#956;m2 respectively. The chemical characteristics of WBSF newlinewas studied using X-Ray Diffraction spectroscopy (XRD) and Fourier Transform newlineInfrared Spectroscopy (FTIR), it was found that the WBSF is the puriest form of newlinepolyamide 6,6 (Nylon 6,6). The tensile characteristics of WBSF were studied by newlinevarying the strands, varying the gauge length and varying the samples, from different newlinemanufacturer which was compared with New Badminton String Fiber (NBSF) from newlinewhich the average tensile strength and modulus of elasticity of WBSF was found to be newline596.89 MPa and 4843.50 MPa respectively newline
