Effect of environment on the integrity of CFRP/concrete bond
The Florida Department of Transportation (FDOT) is one of the leaders in the US on the application of CFRP material for the repair of bridges damaged by vehicular collision or corrosion. As part of an integrated research effort, FDOT sponsored a multi-year experimental study to investigate the long term integrity of the bond between CFRP/epoxy adhesive and concrete. In the study, five competing epoxy systems were evaluated for three disparate exposure conditions representative of Florida's sub-tropical climate. Results were compared with identically prepared specimens kept in a controlled environment. Following completion of exposure, bond integrity was evaluated visually and through destructive testing. The results reaffirmed that bond deterioration was a function of workmanship and surface preparation. It also indicated that visual inspection was limited in its ability to identify degradation. Despite the severity of the exposure, all systems performed satisfactorily.
