Mechanical Properties of Hybrid Fibre Reinforced Concrete With Steel And

The experimental study deals with Hybrid fibre reinforced concrete with the use of (Polypropylene and Recycled polyethylene terephthalate RPET). The M40 grade concrete used was designed by using IS10262-2009 code. The steel fibre and synthetic fibre were added at the volume fractions up to 0.5%. Test results showed that the fibres, when used in a hybrid form, could result in superior composite performance compared to their individual fibre-reinforced concretes. The results indicate that concrete containing a fibre combination of 0.38% steel fibres & 0.12% PET fibres can be adjudged as the most appropriate combination to be employed in HyFRC for compressive strength, splitting tensile strength and flexural strength
