ABSTRACT

The last few decades have been marked by degradation of numerous concrete structures due to the corrosion of steel reinforcements that required costly repair or replacements. In recent years research has been carried out on fiber-reinforced plastic (FRP) bars as an alternative to steel reinforcement. FRP rebars have already shown a promising future to overcome the corrosion problem in many projects, especially in bridge deck and parking garage design.

In this paper long-term bond performance between FRP bars and FRC is investigated and compared with that of FRP bars in plain concrete. The accelerated aging test and pull out test is done. Test results showed that the ultimate and design bond strength experienced noticeable degradation when exposed to combined environmental conditioning. It also showed that bond durability significantly improved owing to the restriction of the concrete crack by the addition of polypropylene fibers.PAGE
