This research investigates the use of environment friendly materials, such as coir fibers, polypropylene fibers, and jute fibers, in concrete. By reducing the diameter of steel bars using fiber ropes, an economical reinforced concrete is produced. The study examines the compressive and flexural strength of fiber-reinforced concrete with the combination of polypropylene fiber, jute fiber ropes, and steel bars. The results show that the addition of fibers enhances the properties of concrete, increasing the flexural strength and compressive strength by 6% and 7% respectively in coir concrete with fiber ropes.
This research work is related to the use of environment friendly materials like fibers of coir, polypropylene and jute in concrete. An economical reinforced concrete is produced by reducing the diameter of steel bar by using fiber ropes. We have examined the compressive and flexural strength of fiber-reinforced concrete. In this study, concrete mix is prepared by using coir fibers. Although instead of using only conventional steel bars, reinforced concrete behavior was investigated with the combination of polypropylene fiber and jute fiber ropes along with steel bars for a constant water binder ratio. These fiber ropes are wound around steel bar with the help of Zepoxy 300 for proper bonding of fiber ropes and steel bar. The results demonstrate that properties of concrete are enhanced by using fibers. Fiber ropes with steel bar in coir concrete increased the flexural strength and compressive strength by 6 and 7%, respectively. Furthermore, it is observed that the addition of fibers in concrete changes the cracking pattern of reinforced concrete beams.
