【 摘 要 】

Fibre-reinforced concrete (FRC) contains fibrous material which increases its structural integrity. The application of irregular arrangement of fibres to concrete altogether upgrades its essential characteristics, for instance, static flexural strength, influence quality, elasticity and flexural stiffness. Filaments are added to cement to control breaking because of plastic shrinkage and to drying shrinkage. This paper exhibits the use of steel fibre, electrical waste copper wire fibre and electrical waste glass fibre of various percentages of volume fractions such as 0.25%, 0.5%, 0.75%, 1.0% and 1.25% incorporated in concrete. Mechanical properties such as compressive strength, splitting tensile strength and flexural strength tests were conducted for normal concrete and fibre reinforced concrete for a curing period of 7 days, 14 days and 28 days. In addition to that modulus of elasticity of concrete for various percentages of fibre content was investigated for a curing period of 28 days. The test results of fibre reinforced concrete were compared with normal concrete to determine the influence of fibres used.
