This dataset contains the raw projection images of time-resolved laboratory based micro-CT data of solute injection experiments in sintered glass, Bentheimer sandstone and Savonnières limestone. The reconstructed (cropped and registered) datasets are available on Digital Rocks Portal (project 221 (DOI: 10.17612/5ww0-gh34) and 264 (DOI: 10.17612/JPVB-JG13)). The data were acquired with a gantry-based micro-CT system specially designed for in-situ imaging (UGCT). The experiments were imaged at 12 or 15 s per scan (full rotation) with a voxel size of 12.95 to 14.6 µm (Bultreys et al., 2016; Van Offenwert et al., 2019). Each fast imaging experiment was preceded by a higher quality pre-scan to determine the static pore structure. Voxel-based or pore-based concentration fields can be quantified based on the reconstructed grey values. Based on this, solute spreading and mixing during tracer injection experiments can be investigated. The raw projection data of this project allows to perform and test reconstruction algorithms. In addition, the data can be used for radiography-level measurements with a time resolution limited to 20 ms.
