Аннотация

A decrease in the strength of cement-sand specimens due to cyclic alternating-sign temperature excitation is shown to yield a shift of the principal maximum and the entire spectrum of the electric response to an impact excitation towards lower frequencies, spectrum broadening, and deterioration of the spectral maxima quality factor.
