Abstract

The aim of this work is investigating the high strength concrete beam using hybrid fibers with different grade of concrete M40 and M50. In this study fiber is added into the concrete in different proportion 0%, 0.5%, 0.75%, 1% for testing the Mechanical properties of concrete cube and cylindrical specimen were prepared and for testing the flexural strength concrete beam was prepared. Polypropylene and ceramic fiber were used in this study ceramic fiber which high temperature resistance so few specimens were has kept in the high temperature oven at 600 °C almost five hrs. Then the flexural strength of concrete beam was analysed and other primary test were conducted for cement coarse and fine aggregate and the experimental result shows the addition polypropylene and ceramic fiber in the concrete slightly improves the compressive, split tensile and flexural strength of high strength concrete.
