Standard for the method of acoustic-emission control of concrete and reinforced concrete products and monolithic structures
Abstract
The new state standard GOST R “Concretes. Acoustic emission control method”, which establishes methods for monitoring concrete and reinforced concrete products and monolithic structures in order to assess damage and early diagnosis of the formation and development of operational (power) cracks by acoustic emission (AE) method, is considered. Unlike traditional methods of non-destructive control and technical diagnostics, the AE method does not require scanning the surface of an object to search for defects, the source of information is the defect itself. Damages are detected long before the onset of the limit state, which makes it possible to plan preventive measures for preventing accidents.
