The ultrasonic technique is used not only to determine the compressive strength or to detect internal structure discontinuities. It is also used to determine the state of deformation and stress in structures and based on the elastoacoustic effect (AE). So far, the AE effect has been recognized quite well in homogeneous materials in the case of porous or heterogeneous materials such as concrete or rock, due to the large dispersion of the results, the study has not been conducted. The subject of the presented research was the use of the AE efect to determine the stresses in small models of masonry made of autoclaved aerated concrete masonry units. The relationship between the value of compressive stresses and the velocity of the longitudinal ultrasonic wave with regard to humidity was presented.
