| Abstract: | The influence of the temperature of cement-sand samples on the electrical signal parameters when the sample is excited by a pulsed mechanical action is studied. A relation between the elastic and electrical characteristics of the samples and the electrical signal parameters is established in the temperature range from 30 to ?40°C. Test results serve as a basis for developing an algorithm for nondestructive mechanoelectrical control of the structural and mechanical characteristics of heterogeneous materials with different temperatures and moisture percentages. |
