Mechanical properties of concrete reinforced with graded pva fibers

Concrete is poor in tensile property due to its brittle nature. Improvement the mechanical properties of concrete carried by combining rebars and fibers concrete. Earlier research state that non-metallic fibres improve pre-crack performance metallic post crack performance. Short resist micro-cracks at an early stage long macro-cracks. The combination short makes much effective. In this study, investigation done on PVA fiber with lengths 6mm (Short fiber) 12mm (Long hybridization 50MPa two stages; first stage, optimum dosage content strength effectiveness strengths carried. Further, second 30% SF + 70% LF, 50%SF 50% LF for finding hybrid combination. Mechanical like flexural strength, split compressive investigated. results obtained are compared mono control mix. parameters observed hybridization. According functionality, showed desired improving overall More improves growth resistance than
