Large SEM-BSE images of hydrated alite-belite mixtures at the ages of 7, 14, 28 and 56 days
This dataset contains a set of images of alite (C3S) and belite (C2S) mixtures (3:1, 1:1, 1:3 in weight). Specimen preparation The powders were mixed before adding water. The water to solid ratio used was 0.5. The specimens were filled in small containers and were allowed to hydrate under a saturated…
A FIB-SEM Protocol for High-Resolution Imaging Combined with EDX Analysis of Cement-Based Materials with Minimized Damage
This is a recording of a talk held at the Microscopy Conference 2025 in Karlsruhe given on 4 September 2025. It shows how lift-out technique helps to avoid artefacts such as shadowing during the FIB nanotomography process and how post-processing is carried out for such a BSE+EDX data set. This dataset…
FIB-SEM nano tomography protocol for high-resolution imaging of cementitous specimens combined with EDX analysis
This data set contains two tutorial videos that demonstrate how focused ion beam nano tomography can be applied to cementitious samples (here a CEM I) in order to image them with as few artefacts as possible. To do this, a volume (approx. 20 x 20 x 20 µm³) is prepared from the bulk material (part 1)…
Animation to visualize the electron beam damage induced in calcium silicate hydrate phases
This dataset visualizes the electron beam damage induced by a scanning electron microscope (SEM) in calcium silicate hydrates (C-S-H). The specimen used is 28 days hydrated alite (water/solid = 0.5). It was scanned using a thermofischer scientific Helios G4 UX microscope at 350 V/25 pA with a stage bias…
