Description
Traditional methods for inspecting reinforced concrete elements often require partial destruction of the material or opening up the structure. In this regard, non-destructive testing methods are becoming increasingly widespread, as they allow the internal condition of a structure to be assessed without compromising its integrity.
The application of X-ray and neutron tomography for non-destructive evaluation of concrete and reinforced concrete structures has been studied.
It is shown that the exponential attenuation model of radiation, described by the Bouguer–Lambert–Beer law, enables quantitative assessment of the material condition and the detection of internal defects such as voids, cracks, cavities, damage to the reinforcement protective layer, and zones of increased moisture.
Linear attenuation coefficients for the main components of concrete mixtures are presented, and their application in the interpretation of tomographic images is discussed. The combined use of X-ray and neutron methods provides a comprehensive analysis of structural condition, taking into account both density and moisture content of the material. This makes it possible to carry out reliable engineering assessments without destroying concrete elements.
The practical significance of the work lies in the ability to plan the repair and strengthening of structures, as well as to justify engineering decisions aimed at improving durability and load-bearing capacity.
The results can be used to develop effective inspection methods, assess technical condition, and predict the service life of construction facilities.
