THE METHOD OF THE NONDESTRUCTIVE DIAGNOSIS INVESTIGATING THE RUSTINESS DEGREE OF THE BEAM REINFORCEMENT

Abstract

We consider the new method of the nondestructive diagnosis that investigates the rustiness degree of the beam reinforcement. The method is based on the difference of the rusty and "healthy" iron permittivity magnitude. Therefore, we can make conclusions about the presence of a rusty beam and the degree of its rustiness by measuring the electric capacity of the beam reinforcement section. In order to increase the reliability of the diagnosis results we suggest setting the additional electrodes on the edges of the working measuring electrodes. These additional electrodes are not connected with the working measuring electrodes.
