FRP Protection And Rehabilitation Of Corrosion-Damaged Reinforced Concrete Columns

This article presents results from two complementary experimental studies related to the protection and rehabilitation of corrosion damaged reinforced concrete columns. The first study was conducted to compare different techniques for protecting steel rebars from corrosion. The methods included three different types of fiber reinforced polymers (FRP), glass/epoxy, carbon/epoxy, and aramid/epoxy; as well as two additional conventional waterproofing systems (a siloxane sealer and polymer concrete overlay). The results show that the FRP materials provide excellent protection against corrosion, even for specimens already damaged by corrosion; the performance of the FRP wrapped specimens is far superior to that of the specimens protected with conventional material systems. The second study dealt with concrete columns that had both axial and spiral steel reinforcement. The FRP of these columns, using glass/epoxy FRP wraps, restored the initial strength of the corrosion-damaged columns and stopped any further corrosion. The authors also note that the ductility of the columns repaired with FRP wraps was increased in comparison to that for the columns with conventional steel spirals.
