Development of a nondestructive method for testing the strength of concrete with a faulted structure based on the phenomenon of mechanoelectric transformations
Concretes are often used in constructions demanding a high degree of reliability; thus, the problem of testing their mechanical characteristics is important from a practical standpoint. This problem can be solved using the phenomenon of mechanoelectric transformations during pulsed mechanical excitation of dielectric materials. Based on these investigations, a method for nondestructive testing of the strength of heterogeneous materials using an algorithm based on using the amplitude-frequency characteristics of an electric signal generated during their impact excitation was developed and patented. An algorithm for nondestructive testing of concrete strength based on the parameters of an electric response to elastic impact excitation has been developed based on experimental studies. The error in determining the strength using the proposed algorithm is 9% for heavy-weight concrete.
