EVALUATION OF SANDSTONE INTERNAL STRUCTURE WITH APPLICATION OF MICRO-CT AND FOTOM SYSTEM
Original language description
The sandstone internal structure is one of the most important factors controlling mechanical properties of this stone. There are many methods ena-bling study of the properties and character of the internal structure. The known methods are based on the penetration of a chosen medium of a detected volume into the pores or they are based on image analysis of rock slices, where fluores-cent colouring highlights the pores. Unfortunately, these methods have a de-structive character and, therefore, it is not possible to use the stone samples again. The possibility to re-use the samples makes the micro-CT a very useful tool. Interpretation of the micro-CT results in combination with the results of other methods may enable more detailed view into the internal structure. We studied widely used Czech sandstones using the micro-CT in the course of our experiment. Next, the acquired data was evaluated in commercial software VGStudio MAX 2.2 and also in our FOTOMNG system. We implemented new specialized module in this system for evaluating of such data. For a measure-ment we prepared several image preprocessing methods. This preprocessing is consisted for example from image binary thresholding for a better diversity be-tween inner porosity and sandstone itself or colour inversion. As addition we implemented function for cropping the samples, due to depreciation of the sam-ple borders caused by repeated measurement. We are able to calculate the value of porosity, for whole series a volume of porespace of sandstone samples or other statistical values. Results and limitations of interpretability are discussed in this article.
