Study on Strength Properties of Fibre Reinforced Concrete

Abstract

This project involves discovering how the addition of fibres in plain concrete mix of M40 grade affects its strength properties. The Strength properties include compressive strength, split tensile strength and flexural strength. The goal of this project is to show that additions of fibres in plain concrete mix significantly improves its strength. This has been done by casting of numerous concrete cubes, cylinders and beams. The fibres used were Polypropylene fibres and Steel fibres. Upon experimenting on these, we have found out that strengths, i.e. compressive strength, split tensile strength and flexural strength has improved significantly. We can thus conclude that fibres impart energy absorption, toughness and impact resistance properties to fibre reinforced concrete material and these characteristics in turn improve the fracture and fatigue properties of fibre reinforced concrete.
