Investigation on Flexural behaviour of Polyvinyl Alcohol Fiber Reinforced Concrete Beam

The primary focus of this research is to examine the impact of incorporating polyvinyl alcohol (PVA) fibre into concrete on its workability and compaction.The study suggests that compared to traditional concrete, PVA fibre-reinforced concrete exhibits superior strength.PVA fibre is identified as one of the top polymeric fibre for reinforcing concrete.Previous research suggests that an optimal dosage of 1.5% PVA fibre leads to improved performance across various tests.This paper outlines the experimental setup and results obtained from flexural strength, split tensile strength, and compressive strength tests conducted on cubes, cylinders, and prisms after curing for seven and twenty-eight days.Flexural strength assessments are specifically conducted after a twenty-eight-day curing period.Among the numerous advantages of Fiber Reinforced Polymer (FRP) reinforcements are their high tensile strength, resistance to corrosion, nonmagnetic properties, lightweight nature, and ease of handling.Recent studies highlight various fibre types including polypropylene, steel, glass, and polyvinyl alcohol as suitable options.Earlier investigations recommend a maximum overall fibre content of 3% in concrete.Additionally, the aspect ratio of fibre emerges as a critical characteristic requiring careful consideration.ANSYS software is used to examine the behaviour of normal concrete beams with the findings of polyvinyl alcohol fibre reinforced concrete beams.The study compares these results.
