Study the Effect of Polypropylene Fiber with Steel Slag Aggregate in Concrete

India leading developing country in world. In future high strength high performance concrete required for construction work. Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. The character of fiber-reinforced concrete changes with varying concretes fiber materials, geometries, distribution, orientation, and densities. Steel slag which is produced as a waste material in the steel industry and has a negative impact on environment when disposed. Steel slag was found to be the best replacement for fine aggregates of concrete. Making use of steel slag in construction industry helps for the mass utilization of waste material prevents the depletion of natural resources, cost reduction, protect and preserve environment. Polypropylene fiber is also a light weight synthetic fiber. It prevents crack formation and provides reinforcement to the concrete structure. In this project work polypropylene fibers of different percentage (0.5 %, 1 %, 1.5 %, and 2 %) added with optimum replacement of steel slag for the fine aggregate in concrete. Tests on workability, compressive strength, flexural resistance, split tensile strength, modulus of elasticity were conducted on specimens.
