Abstract
In the last 20 years, the use of Fiber Reinforced Polymers (FRP) as internal concrete reinforcement has gained a lot of interest worldwide.
Many applications have been reported in the literature to demonstrate their use in infrastructure applications to make use of their superior non-corrosive and non-conductive performance.
The contribution of the Egyptian researchers in this field has been
restricted as this type of reinforcement is hardly available in the local market. On the other hand, the imported product is expensive and the selection alternative, with respect to the bar type, diameter size and
surface configuration are limited.
This investigation is carried out to study the bond behavior of reinforcing GFRP bars and concrete. Due to the scarcity of FRP bars, the research started by manufacturing the FRP bars needed for this investigation. In-house manufacturing of FRP bars has been described in the literature using locally available glass fiber roving and polyester to produce mono type GFRP bars.
To improve the bond between concrete and Glass Fiber Reinforced Polymers (GFRP) bars, different surface treatments are applied during
the manufacturing process. Spiral strand surface, enlarged bar ends for
mechanical bond and sanded coating of bars are use-d. After manufacturing the GFRP bars a tensile test for some specimens are carried-out and results is reported. And to compare this with the steel
