An Experimental Study on the Evaluation of Injection-ability for Concrete Crack-Repair Materials by using Ultrasonic Pulse Measurement Method.

초음파 측정법을 이용한 콘크리트 균열보수재의 충전성능 평가에 관한 실험적 연구

A concrete is easy to happen crack. So it requires crack-repair work to solve quality deteriorations of a building because of cracks. When crack is filled with crack-repair materials, it is difficult to find out how depth it was injected. So in this study we evaluated the injection depth with using indirect and oblique methods, ultrasonic pulse measurement method of NDT. The results of this study showed that both methods are possible to evalute penetration depth of crack-repair materials and indirect methods is thought to be more useful one than obliqure one.
