Micro-CT Dataset of Cemented Sand Specimens under Uniaxial Compression with Varying Cementation Degree

Computed tomography (CT) is an X-ray–based imaging technique that enables high-resolution analysis of the internal structure of materials. During scanning, X-rays are attenuated while passing through the specimen (depending on density and composition), and a three-dimensional volume is reconstructed from multiple two-dimensional projections acquired at different rotation angles. In this study, CT was used to investigate the microstructure of cemented sand specimens subjected to uniaxial loading, with a focus on identifying the spatial distribution of grains and cement binder as well as the pore structure. The resulting volumetric data support microstructural characterization and serve as input for subsequent numerical (FEM) modelling. The dataset provides the raw, unprocessed CT image stacks as acquired. The CT data consist of reconstructed slice images (i.e., cross-sectional slices already reconstructed from the original projection views). The CT data were acquired at the 3SR Laboratory at Université Grenoble Alpes. Note that the first and last slices are typically not suitable for quantitative evaluation (e.g., due to boundary effects and reconstruction artefacts) and may be excluded during post-processing.
