Abstract

Multi-wave testing allows to improve the metrological performance and to enhance the usefulness of the ultrasonic method of passing when in the determination of physical and mechanical properties of concrete. The article discusses the possibility of joint use of longitudinal subsurface waves and Rayleigh waves to determine the dynamic Poisson ratio of concrete structures in full-scale conditions, practical results.
