Estimating Crack Depth of Concrete Structures Using Ultrasonic Pulse Velocity

Abstract:

The concrete structures have the quite close linkage on the human life and it is used for a long time. Therefore, the importance for structure safety had been being continuously increased. The general method in order to measure concrete crack is the non destructive inspection. This method is known efficiently when it is difficult to check the crack through the eyes because of not exposed. Hence, the purpose of this study is measuring a crack depth of concrete by using the ultrasonic pulse velocity. And the Pundit that is one among the supersonic equipment was used in order to proceed with this research. In the first place used the existing methods (Tc-To, BS, T, close range bypass wave) in order to estimate crack depth of concrete. And then new method that the BS method and the T method are combined make an attempt to analyze the error.
