Experiments on Steel Specimen for Concrete Crack Measurements

콘크리트 균열 탐사를 위한 철제시편 비교 실험

The various size and shape of cracks in concrete induce deterioration of reinforced concrete structures including nuclear power plants. The wider and deeper the crack is, the concrete structures are more vulnerable to carbonization. Thus, it is essential to develop a reliable measurement technique of cracks inside concrete. In this study, an ultrasonic test method is applied to the crack measurements. The results can be used for evaluation of existing reinforced concrete structures.
