Open publisher page 0 citations

Abstract

The principle of electrochemistry is adopted in this test.The current is switched on 7 RC beams and 5 RC pillars strengthened with CFRP of different measures which work in corrosive environment for a long time.So the corrosion speed of the Components 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.Some suggestion in engineering is given.The test results indicate that the durability of the Components strengthened with CFRP can be enhanced with different degree.The effect of improving the durability is related to the strengthen method of the components.
