Fibre reinforcement strategies for enhancing ductile behaviour in concrete elements

Steel is costly and detrimental to the environment when used as a reinforcement. Another technique for reinforcing concrete is fibre reinforcement. Fibre is a small amount of reinforcing material with specific properties. Fibre-reinforced concrete has several uses and is available in several shapes. Cellulose fibre, glass fibre, steel wire fibre and steel raw material have the following percentages: 0.5%, 0.7%, and 1%; 0.3%, 0.6%, and 1%; and 0.5%, 1%, and 1.5%, respectively. Specific percentages of different fibres, ranging from 0.3% to 1.5%, are employed in this study to assess the ductile behaviour of concrete since the primary objective of utilising these fibres is to enhance the ductile qualities of concrete. The fibre-added specimens are subjected to four distinct kinds of tests. It has been demonstrated that concrete’s flexural strength, split cylinder strength, and double punching strength have increased by up to 28%, 60%, and 93%, respectively, compared to the control mix concrete. Steel and raw material fibre exhibited no detrimental impacts on compression at certain percentages; however, glass fibre and cellulose fibre reinforcements had detrimental effects, reducing the compressive strength by up to 33.5% and 49.3%, respectively.
