On the relationship between the parameters of the electric response to pulsed mechanical exposure and the formation of cracks in concrete

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.
