X-ray computed tomography analysis of four test specimens of concrete before and after the frost-resistance test

The non-destructive 3D X-ray computed tomography method was used to visualize the structure and baseline analysis of changes in the internal construction of two samples of concrete, four test bodies subjected to the frost resistance test. The analyzed samples were scanned on the Nikon Metrology XT H 450 2D / 3T CT Scanner. CT imaging was performed using CT Pro 3D software. The visualization, the preparation of tomographic sections, the analysis of the pore space and the measurement of the dimensions of the test of the bodies were elaborated in VGStudio MAX 2.2 software
