Abstract

An experimental study of the effects of polypropylene fiber reinforcement on the bond between concrete and conventional mild steel reinforcement has been carried out. Two fiber lengths, four fiber contents and two different water to cement ratios were used in this study. Differences in bond stress versus bond slip behavior due to the above variations were investigated using ASTM Standard Test Method C 234 - 71. A second test was designed and used to indicate changes in transfer lengths caused by the above variations. Results show that the polypropylene fiber reinforced concrete (PFRC) studied possesses bond strength (between concrete and reinforcing steel) qualities equal to or slightly better than those of conventional concrete.
