In this article, an innovative new method of non-destructive testing for estimating the sensitivity of limestone is presented. An advantage of the laser ultrasonic structuroscopy method is the time and the quality, due to which less tests are necessary for an analysis of rock properties. Limestone is measured with an innovative structural control method, which shows a good qualitative and quantitative agreement with the basic structural analysis.
