Prestressed Concrete, Bonded Tendons, Bond Performance, Compressive Strength


Corrosion has been a persistent problem causing the failure of post-tensioned tendons in segmentally constructed bridges. To address this issue, the impregnation method has been considered where the corrosion-mitigating fluids are pressure injected into the interstitial spaces between the seven wires of steel strands. A previous study showed that this method was able to arrest corrosion. However, it compromised the bond strength between the steel and the strand. For that reason, this study aims to identify a fluid that can be impregnated into the interstitial spaces without sacrificing bond performance. The most promising fluid found in the study is an inhibiting fluid traditionally used as coatings on reinforcing bars, which had minimal impact on grout properties. Ongoing research will determine whether it effectively mitigates corrosion.
