Understanding the Effect of Adding Polypropylene Fibers to Concrete Beam

Jeevan N, Amoghavarsha KV

Abstract: The main goal of this study was to make concrete stronger by finding the best amount of polypropylene fibers to mix in. Fiber-reinforced concrete is widely used in construction because it helps improve performance. In this project, we checked how adding different amounts of polypropylene fiber affects the strength of concrete-both its ability to handle pressure (compressive strength) and bending (flexural strength). We did this by making and testing concrete cubes of 150mm ? 150mm ? 150mm. After identifying the most effective fiber content through these tests, we used that same mix to make larger beam-like samples and tested them too. The results showed a clear improvement in strength after 28 days, and the ideal fiber content was found to be 1.5% of the cement volume.

Keywords: polypropylene fiber, compressive strength, flexural strength and fiber reinforced concrete
