Development of method of evaluation of concrete damage in the process of cyclic freeze-thawing

Abstract

The research presents a new method for determination of concrete damage under cyclic freezethawing by the parameters of the electrical response under impact excitation. It is established that the attenuation coefficient of the energy of the electrical responses under impact excitation can be used as a diagnostic criterion for crack process determination. A higher accuracy of evaluation of crack processes by the parameters of the electrical signal in comparison with the acoustic method is shown.
