This data set contains data of scans of three separated dry salt crusts that formed by evaporation of magnesium sulfate solution with 0.64 mol/L initial concentration from F32 quartz sand at 40%, 30%, and 20% saturation inside the sand packing. The cylindrical sample holder from polymethyl methacrylat (PMMA) had a diameter of 31 mm and a wall thick... |

Ruf, Matthias; Balcewicz, Martin; Saenger, Erik H.; Steeb, Holger, 2021, "Digital rock physics: A geological driven workflow for the segmentation of anisotropic Ruhr sandstone: micro-XRCT data set", https://doi.org/10.18419/DARUS-1152, DaRUS, V1
The Ruhr sandstone is assigned to the Upper Carboniferous and is part of the Ruhr cyclothem located in North Rhine-Westphalia, which consists of clays, siltstones, mudstones, sandstones, and interbedded coal seams. The sediment was chemically and mechanically compacted, folded, and faulted during the Hercynian orogeny. The studied microstructure of... |

Ruf, Matthias; Steeb, Holger, 2020, "micro-XRCT data set of Carrara marble with artificially created crack network: fast cooling down from 600°C", https://doi.org/10.18419/DARUS-682, DaRUS, V1
micro-XRCT data set (projection and reconstructed images) of a Carrara marble core with a diameter of 5 mm. The sample was extracted with a water-cooled diamond drill from a bigger sample with a diameter of 30 mm and a length of 80 mm which was before subjected to following thermal treatment to initiate cracks: Starting at room temperature (20°C) t... |

Ruf, Matthias; Steeb, Holger, 2020, "micro-XRCT data set of an in-situ flow experiment with an X-ray transparent flow cell", https://doi.org/10.18419/DARUS-691, DaRUS, V1
Micro-XRCT data sets (projection and reconstructed images) of an in-situ experiment with an X-ray transparent flow cell. As a porous medium, a 3 mm cylindrical sandstone core from the County of Bentheim was investigated. The conceptual design of the cell was presented in Fusseis et al. (2014) and offers the possibility to apply a confining and back... |

Ruf, Matthias; Steeb, Holger, 2020, "micro-XRCT data set of open-pored asphalt concrete", https://doi.org/10.18419/DARUS-639, DaRUS, V1
micro-XRCT data set (projection and reconstructed images) resulting from a region of interest scan (diameter 48.41 mm, height 35.46 mm) located in the center of an open-pored asphalt concrete core with 100 mm diameter and 50 mm length. |
Mar 5, 2020 - Publication: Digital rock physics and laboratory considerations on a high-porosity volcanic rock
Schepp, Laura L.; Ahrens, Benedikt; Balcewicz, Martin; Duda, Mandy; Nehler, Mathias; Osorno, Maria; Uribe, David; Steeb, Holger; Nigon, Benoit; Stöckhert, Ferdinand; Swanson, Donald A.; Siegert, Mirko; Gurris, Marcel; Saenger, Erik H.; Ruf, Matthias, 2020, "Digital rock physics and laboratory considerations on a high-porosity volcanic rock: micro-XRCT data sets", https://doi.org/10.18419/DARUS-680, DaRUS, V1
Reticulite (high-porosity volcanic rock) is a pyroclastic rock formed during intense Hawaiian fountaining events. 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... |
