Bond strength has great significance in structural properties of reinforced concrete structure because bond strength is responsible for transfer of forces between two composites materials i.e. steel and concrete. Insufficient bond can decrease the load carrying capacity and resistance of the structure when subjected to different loading conditions. To study the bond strength different tests were carried out using plain and with addition of steel fibers. Pullout tests were carried out to study

A total of 144 specimens were cast and tested in the present investigation. The main variables considered were the volume fraction of crimped steel fibres, volume fraction of hook end fibres, gloved fibres and the diameter of reinforcement bars. The variation in steel fibre percentage is considered in this study to check the effects of them on bond strength & also the effect of bar diameter. Various percentages of fibres as 1%, 1.5% & 2% of the total volume of the concrete is used in the recent study.
