The honeycombed network of bubbles is supported by glassy threads and forms a structure with a porosity of more than 80 %. It is an end-member for high-porosity materials with a high stiffness and brittleness. For this specific material, hydro-mechanical experiments are very difficult to perform. Therefore, digital rock physics plays an important role. Digital rock physics combines microtomographic imaging with advanced numerical simulations of effective material properties. It is used to complement laboratory investigations with the aim to gain a deeper understanding of relevant physical processes related to transport and effective mechanical properties. <br> Two micro-XRCT data sets of two dry cubic reticulite samples under ambient conditions scanned at two different resolutions are provided ("Reticulite-01_AxMF01.rar" and "Reticulite_03_AxMF01.rar"). Further, for each of this data sets a subvolume with 400 x 400 x 400 voxels was extracted and segmented (binarized) into skeleton and pore space which are also provided ("Segmented_subsamples.rar") and can directly be used for digital rock physics. A third cubic reticulite sample was saturated with distilled water in three steps (500 microliters, 250 microliters and 250 microliters) with help of a pipette which was not removed during the CT scans. After each injection a scan was performed. The data sets are named according to the complete injected fluid volumes (“Reticulite-AxHP_wet_500ul.rar”, “Reticulite-AxHP_wet_750ul.rar” and “Reticulite-AxHP_wet_1ml.rar”).Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany's Excellence StrategyEXC 2075 - 390740016
