Abstract
This paper presents an experimental investigation on the polypropylene fibre reinforced fly ash concrete RC beams under flexure. The variables of study include the polypropylene fibre content (0.2 % & 0.4%). The polypropylene fibre and 10% of Fly ash as cement replacement are incorporated in all the concrete mix proportions considered in this study. The experimental test results showed that the compressive strength of concrete increases with the increasing percentage of fibre. The flexural strength of polypropylene fibre reinforced fly ash concrete beams increased considerably than the control concrete beams.
