A method for estimating the impregnation rate of polymer-impregnated concrete was investigated using the propagation characteristics of sound. The sound transmitted from experimental bodies can
differ depending on the impregnation ratio. In this study, the impregnation rate was estimated by measuring the change in the propagation characteristics of sound and using machine learning. The
study results confirm the validity of the research method.
