Abstract

The relationship between the parameters of acoustic emissions and the electric response to pulsed mechanical excitation of high-density concrete and the stages of deflected mode that is formed by external compressive loadings was studied. It was established that the attenuation coefficient of the electric-response energy increases considerably when a concrete sample passes from elastic deformation into the fracturing zone.
