Micro-computed tomography The micro-CT measurements presented in this paper were performed using RXCT X-ray CT scanner from Geotek. The measurement station includes: Geotek RXCT (Rotating X-Ray And Computed Tomography) CT scanner, Geotek MSCL-XCT 4.0 software for operating the tomograph, Geotek Image Reconstructor program, responsible for reconstructing measurement data. The RXCT is equipped with a Thermo Kevex X-ray Inc. Type PXS10-65W X-ray tube, featuring a maximum power of 65 W at an accelerating voltage of 130 kV. The device allows examination of samples up to 15 cm in diameter and 150 cm in length. The resolution of the obtained images is from 40 to 300 um. 2.3. Micro-CT Image Processing The 3D results of analyzed samples were investigated using poRose software (Madejski et al., 2018) to visualize and compute total porostiy before and after damage (Figure 2-3). Total porosity of analyzed sample, calcualted before damage was about 5.9%, when porostiy after tensile tests increses up to 10.2%.
