홈페이지논문 초록 (Abstract)
The structure must be periodically checked and measures must be taken to prevent deterioration in building construction. From this point of view, a nondestructive test is essential to estimate whether the construction of buildings is proper, and whether the dimension o f depositing concrete is consistent and without damage. This study estimated the thickness of the concrete component of constructio n framework using the ultrasonic velocity method and the impact ec ho method, in order to investigate reliability of the estimation of the thickness of normal strength concrete and high strength concrete , leading to the following conclusions. In the estimation of the thickness of the concrete structures, specimens of normal stre ngth of 24MPa and specimens of high strength of 40MPa demonstrated an average error rate of 5.1% and 2.2%, respectively. The impact-echo me thod, one of the non-destructive tests, is verified as an efficient dia gnostic technique. With this information, we will determine specific standards for the maintenance of structures, and the re-creation of lo st building blueprints.
