Study on High Strength Concrete with Hybrid Combination of Steel and Polypropylene Fibers
In this work, aimed to improve the mechanical properties of concrete with hybrid fibers (HF) for M50 grade of concrete with mix proportion of 1:1.67:2.22 with a w/c ratio of 0.40. Totally 13 mixes were prepared in that one mix is considered as control (without hybrid fibers) and other twelve mixes with different proportions of (HF)-Steel (S) and Polypropylene (P&PP) are added. The proportion of steel and polypropylene fibers are added, each with different hybridization ration i.e. S0P0, S1%, S2%, S3%, P0.2%, P0.25%, P0.3% with the combination of steel fibers and PP with S0.8%P0.2%, S1.75%P0.25%, S2.7%P0.3%, S1%P0.2%, S2%P0.25%, S3%P0.3% are added in volume fractions. Nano-silica (NS) of 0.75%is added in to the concrete mix. The properties such as compressive strength, split tensile strength, impact resistance, and sorptivity for all the mixes were studied. Based on the test results, fiber combination of 2% steel with 0.25% PP fiber shows improved compressive strength, split tensile strength and less percentage of water absorption. Hybrid combination of 2% and 3% steel with 0.25% and 0.3% PP fiber enhanced the impact performance based on numbers of blows and impact energy at first and final failure. The hybrid steel – polypropylene fiber in the mix performs better in strength and durability properties than control and mix with only steel and polypropylene fibers.
