Structural Strength Enhancement of Rigid Pavement using Scrap Metal Fibre Reinforcement

Road construction with the use of steel fibers to improve the strength and reduce maintenance is an efficient technology established in current times by many researchers. In this study we will utilize this advantage of steel fibers but instead of buying typically available steel fibers we will utilize the locally generated metal scrap fibers in the construction of road pavements. The objective of present paper is to investigate the feasibility and performance of concrete when mixed with metal scrap For this the main aim is to develop a M40 grade mix design concrete with partial replacement of crush sand with metal scrap fibers in the percentage of 5%, 6% and 7% by weight of concrete. By conducting durability and compressive tests on this concrete the optimum percentage of metal scrap utilization in concrete will be presented. Comparisons are made with conventional concrete of M40.
