Description
The ultrasonic research method for studying the structures and determining the possible presence of defects has been known for a long time and has been successfully used to solve various issues directly at construction sites. However, this method has a number of disadvantages, such as the low speed of work and the lack of visual visualization of research results. At the same time, the new technological GPR method is devoid of such disadvantages and, on the contrary, is characterized by high speed and visibility of research results.
This article presents the results of field studies of vertical reinforced concrete structures by comparing ultrasonic and GPR methods. As a result of the research, it has been shown that with using of modern non-destructive inspection methods of structures, such internal defects of concreting as pores, cavities, voids and disintegration can be detected efficiently and with high speed. The research results can be presented visually and allow you to more accurately position the location of defects, as well as build 2D and 3D maps of the location of defects.
