Связь параметров электрического отклика на ударное воздействие с качеством контакта цементной матрицы и крупного заполнителя в бетоне

Abstract

The work presents the research results of the parameters of the electric response to impact excitation of the heavy concrete samples with different quality of contact of the cement matrix and coarse aggregate. It is established that a change of the contact zone characteristics lead to the transformation of the spectra of the electric responses, shift of the spectrum towards lower frequencies and decrease in the attenuation coefficient of the energy of the electric responses.
