CT-Scan of ASR reacted samples

Today I have been busy with a trial CT-scan of RILEM AAR-4 samples. The Main aim was to get a 3-dimensional view on how cracks were distributed in concrete medium. Following 3 videos show Top, Front and side view respectively. While progressing through the sample, we can see how cracks are located and progressed.

Current sample size is 15mm x 15mm x 7 mm, resolution of images are around 13 microns\pixel. Largest observed crack width is roughly 80 microns.
