Comparative Analysis of Steel Fibre Reinforced & Coir Fibre Reinforced Concrete with Conventional Concrete

Fibres have been used to improve concrete, which is often brittle and weak in stress. The use of asbestos to strengthen pottery, horse hair in plaster, and straw in mud bricks were the first materials used in this process. Conversely, continuous reinforcement is used to maintain reinforced concrete, but it requires a great deal of skill and accuracy. On the other hand, discrete fibre placement in plain or reinforced concrete appears to be more promising. In order to increase the compressive strength of concrete, this study investigates the possibilities of using steel and coir fibre as an efficient and sustainable reinforcement material. The development of fibre-reinforced concrete (FRC) in the early 1960s demonstrated that concrete might be transformed into uniform, isotropic materials. FRC's strength and ductility are increased by the randomly distributed fibres, which stop cracks from forming and spreading once concrete does. If the right amount and distribution of steel fibre in the concrete matrix are guaranteed, the steel wires in tires can be used effectively in concrete. On the other hand, adding coir fibre to the concrete structure improves its tensile and flexural qualities. Additionally, coir fibre is typically found in nature and is environmentally friendly. Bond failure between the fibre and matrix or material failure are the two primary failure modes for fibre reinforced composites. In order to assess the strength and durability characteristics of hardened concrete, we examined the performance of various fibres utilized at varying percentages by weight of cement. According to earlier research, adding fibres to such concrete barely changed its compressive strength, but also seemed to impair its flexural and tensile strength, which eventually affected the concrete's qualities. The uses of fiber-reinforced concrete are also covered in this paper, along with the numerous efficient ways it may be used to increase strength and improve crack resistance. In order to assess the strength characteristics of hardened concrete, we examine the performance of steel and coir fibers at various percentages, ranging from 5%, 10%, and 15% by weight of cement. Different concrete grades, such as M20, M25, and M30, are taken into account in the study for accurate evaluation.
