Short summary
In this study, a specimen of sand was scanned to evaluate pore structure quantitatively using a micro-focused X-ray CT scanner. The representative volume to perform reasonable image analysis for sand was discussed, and then the spatial distribution of pore diameter in 3-D was visualized and evaluated quantitatively by granulometric image analysis. Also, the voxel-percolation analysis was newly proposed in this study to assess capillary pressure and saturation degree by pore diameter analyzed.
In this study, a specimen of sand was scanned to evaluate pore structure quantitatively using a...
