Raw projection data of 8 repeat micro-CT scans of 12 s each (recon1 - recon8) was acquired when the sintered glass sample (6 mm diameter) was saturated with demineralized water. The EMCT micro-CT scanner (designed and built in collaboration with TESCAN XRE, Belgium, www.xre.be) at UGCT (Ghent University, Belgium, www.ugct.ugent.be) was used with an accelerating voltage of 130 kV and a target power of 16 W. Every (back-to-back) scan consists of 600 radiographs (exposure time 20 ms) acquired over 360°. The different rotations (scans; zip files) can thus be reconstructed individually or can be recombined to different reconstruction intervals. Information about the scan parameters can be found in the attached text file. Dark field and flat field images are provided as well (respectively di.tif and io.tif).
