A Study of Flexural and Bending Strength of Steel, Polypropylene and Hybrid Fibre Reinforced Concrete without Adding Admixture

The present study has been taken up for evaluating the different types of concrete. Emphasis has been given to the strength and deformation properties of reinforced concrete beams. This paper presents the results of an experimental investigation carried out on four different types reinforced concrete beams, 150 mm × 150 mm × 700 mm in size. The beams were tested under one-third point loading. The results exhibited that the flexural strength of concrete are meaningfully improved by adding steel, polypropylene and hybrid fibers. Out of the three different types of fibers used in this study, the fibers with steel and hybrid showed better efficiency in improving the flexural response.
