Open publisher page 0 citations

Abstract

The principle of electrochemistry is adopted in this test.The current is switched on 7 RC beams strengthened with CFRP of different measures,and these beams have worked in corrosive environment for a long time.So the corrosion speed becomes fast.Comprehensive comparison of mechanical property and transformation rule among them has been made.The different effects of the enhancement in durability are analyzed and its reason is researched.The test results indicate that the durability of the beams strengthened with CFRP can be enhanced significantly especially in the beam strengthened with CFRP entirely.
