Description in English
This project is focused on the application of industrial X-ray computed tomography (CT) for the characterization of shotcrete under complex environment of deep underground space. The aim is to perform a series of CT measurements, from which the parameters of the observed material will be obtained. The result will be a characterization of the internal structure based on porosity, determination of defects and changes in the degradation proces. The additional information of the material will be gained by means of chemical mapping using Laser-induced breakdown spectroscopy. The results of the studies will help to understand aging/degradation processes of concrete during the longterm effect of mine enviroment, it will help to determine limitation of save loading according to concrete condition and it will be used to optimize the process of application of shotcrete in deep mines.

Key words in English
