摘要

The application of stainless-steel bar, Fiber Reinforced Polymer (FRP) bars, bamboo bars and aluminium alloy bars as alternatives for steel rebar in construction is limited due to certain drawbacks like low modulus of elasticity, reduced stiffness, etc. To address these challenges, in this study proposes advanced alloy formulations to develop new materials called reinforced aluminium or Aluminium Metal Matrix Composites (AMMCs), making them more suitable for concrete applications. The various properties like tensile strength, yield strength, percentage elongation and Young’s modulus of reinforced aluminium were examined to concludes the feasibility of using reinforced aluminium as reinforcement in concrete structures. It was observed that the reinforced aluminium achieved Young’s modulus of 201.93 GPa, % elongation of 22, tensile strength of 399 MPa and yield strength of 869 MPa, meeting various IS and ASTM reinforcement standards for concrete applications. The findings concluded that the reinforced aluminium can be used as alternative to steel reinforcement in concrete applications.
