Abstract

This study presents strength properties of concrete reinforced with steel-polypropylene hybrid concrete and compared it with steel fiber reinforced concrete and polypropylene concrete. Hybrid Fiber Reinforced Concrete (HFRC) is formed from a combination of different types of fibers, which differ in material properties, remain bonded together when added in concrete and retain their identities and properties. The combining of fibers, often called hybridization, is investigated for a M40 grade concrete. The fibers used polypropylene and steel (crimped) fibres with different fiber proportions of steel and polypropylene. Compressive test and split tensile strength were performed and finally the result was extensively analyzed to associate with above fiber combinations. Based on experimental studies, the paper identifies fiber combinations that demonstrate maximum compressive and split tensile strength of concrete.
