Abstract

The article proposes a method for evaluating damage to reinforced concrete subjected to uniaxial compression and four-point bending. The method is based on measuring and analyzing the parameters of electric and acoustic emissions and electric response to impact. It is established that the main signs marking the start of the cracking process are: the appearance of high-amplitude acoustic and electromagnetic emission signals changes in the spectral composition of the electrical signal, and the increased attenuation coefficient of the electric response's energy. Continuous or recurrent monitoring can be used to assess deterioration processes in reinforced concrete subjected to mechanical stress.
