Abstract: An experimental investigation has been carried out to determine the effect of fibers on the bond strength of different grades (M20 and M50) of concrete by using reinforced bars of different diameters(10mm and 12mm). Different types of fibers such as glass, polypropylene, basalt were used in the preparation of concrete mix with 0.25% of volume proportion. Then the bond strength was determined by the pull-out test as per IS 2770 (part 1). Based on the test results of the study, grade of concrete, type of fibers and different diameter of reinforcement bar are the key parameters that affect the bond strength of concrete. The contribution of basalt fiber in enhancing the bond strength was found to be more significant compared to other fibers (8.227 N/mm2 for M20 concrete and 9.323 N/mm2 for M50 concrete). The bond strength has been improved slightly by increasing the diameter of the reinforcement bar. Durability analysis was carried out by curing specimens in HCl and H2SO4. Fibers don’t have sufficient influence in the durability of concrete.
