Abstract
Background: Fiber-reinforced concrete is a material of choice for enhancing the performance of concrete structure by improving their mechanical properties.
Objectives: The study aims to understand the effects of adding waste fiber material, such as rivet mandrels and wire fibers, on the behavior of concrete and how it influences the workability, compressive strength, tensile strength, modulus of elasticity, and stress-strain relationship of concrete.
Methodology: Experiments were conducted to observe the effects of adding fiber material on the workability, density, compressive strength, and tensile strength of concrete, while finite element analysis tested the effects of adding the same proportions of the previous material to the elastic modulus and stress-strain relationship of concrete.
Results: The study shows that adding waste fibers generally enhances the mechanical properties of concrete up to a certain percentage, beyond which these benefits start to decline. Wires gave better results due to their higher aspect ratio compared to the revit mandrels.
Conclusion: The study concludes that it is possible to enhance various mechanical properties of concrete by making use of waste fiber material and reduce the costs of producing traditional concrete.
