Testing of Concrete by Contactless Non-Destructive Tomographic Method

In this paper are described the experimental studies performed for determining the structure of concrete, assessing and successful identification of the location of defects and imperfections in the surface and inside of cored specimens, taken from reinforced concrete elements at age of concrete 1926 days. A contactless non-destructive tomographic method was used and the possibility of its application for conditional assessment of existing buildings and facilities is described. Two- and three-dimensional images were obtained. Studies have been made at different depths of rays penetration. Device Nikon XT H 225 was used. Data processing was performed with the software Volume Graphics, MyVGL.
