Detection of Internal Defects and Failures of Concrete Structures Using Non-Destructive Methods

Abstract

This paper deals with the issue of detection of internal defects and failures of concrete structures with emphasis on the use of non-destructive methods. All parts of the structure that reduce its service life or bearing capacity can be considered as internal defects and failures. These are, for example, gravel nests, cracks, delamination, caverns etc. Due to the prevalence of concrete structures, the development of this part of diagnostics is very important both for the safety of their users and to reduce the economic costs of their future repairs.
