A Study on the Application of Non-destructive Test for Concrete Bridges in Korea

국내 콘크리트 교량에 적합한 비파괴 시험법 적용에 관한 연구

Non-destructive field tests of the concrete has achieved increasing acceptance for the evaluation of existing concrete structures. But the application of this test has not still accomplished to guarantee perfectly the durability of the concrete bridges in Korea. As two major testing methods, this paper recommends the proper empirical relationship between the rebound number together with the ultrasonic pulse velocity and the core strength. Also, this paper recommend the relationships as the aging and as the element.
