The authors offered and experimentally justified a way to increase the accuracy of the electromagnetic emission method to determine the strength of concrete. The method is based on the phenomenon when nonmetallic solids during their mechanical excitation generate electromagnetic emission. Amplitude-frequency characteristics of the electromagnetic response to the impact excitation of concretes are used to determine the strength of these materials. The paper describes how tests are conducted and presents a dependence between the strength of concretes and the amplitude-frequency parameter.
