Corrosion Resistance and Bond Behavior Research of Corrosion-damaged Reinforced Concrete Wrapped With CFRP

Carbon Fiber Reinforced Polymer/Plastic ( CFRP) can resist corroding because they are relatively watertight and airtight. CFRP can be used to strengthen the reinforced concrete structure because of its high strength and good corrosion resistance. This test will research the corrosion resistance and bond strength of corrosion-reinforced concrete wrapped CFRP subjected to corrosion again. The differences between CFRP and the conventional protective systems ( silicon alkyl and polymer mortar ) were discussed in this article. This test indicated corrosion-reinforced concrete wrapped CFRP will restore the bond strength between corrosion-reinforced and concrete column and arrest further corrosion.
