Experiment Study: Sisal Fiber Reinforced Concrete
Abstract
One of the main fields of research that is becoming more and more relevant is fibre reinforced concrete. Fibers are used to enhance the tensile qualities of concrete without reducing its compressive strength. This study attempted to examine the impact of natural sisal fibre on concrete by partially substituting cement. For usage in concrete, sisal fibre is chemically processed in this instance. When compared to standard M25 concrete, fibre reinforced concrete with 1%,2%,3% of fibre replacing cement by volume has mechanical parameters such as compressive strength, split tensile strength, and flexural strength that are higher. Comparing fibre replacements of 1%, 2%, and 3% to ordinary concrete, the compressive strength at 28 days increased by 13.8%, 21%, and 16.3%, respectively. When compared to normal M25 concrete, fibre substitutions of 1%, 2%, and 3% enhance split tensile strength at 28 days by 24%, 56%, and 80% and first cracking load in flexure by 12.5%, 27.5%, and 20%.
