A method for non-destructive testing of reinforced concrete based on the phenomenon of mechano-electric transformations is proposed in this work. The procedure for assessing damage in concrete is based on the measurement of an electric response to a weak elastic impact. It was found that the moments of crack formation and growth during bending are accompanied by a significant decrease in the correlation coefficient of the electric responses spectra and by a stepwise change in spectrum shift (at frequency domain) at which the maximum correlation coefficient is observed. It was determined that the increase of energy attenuation coefficient of the electric response can serve as a forerunner of a catastrophic destruction in concrete. The diagnostic criteria proposed in this work can be used for monitoring the damage processes in reinforced concrete under bending conditions.
