FIB-SEM dataset of 7d hydrated alite prepared using laser-ablation
This dataset contains a FIB-SEM volume of a 7-day hydrated alite sample. The sample was prepared using an fs-laser to obtain a large volume and sliced using a Ga-FIB-SEM. The dataset was prepared as a proof of concept demonstrating the applicability of fs-laser preparation for hydrated cementitious materials,…
FIB-SEM nano tomography (3D BSE and EDX) on hydrated CEM I utilising the lift-out-method
This dataset contains an image stacks depicting 28 days hydrated cement mortar (CEM I). The volume was created using a scanning electron microsope (SEM) in backscatter electron mode (BSE), combined with energy dispersive X-ray spectroscopy (EDX) and a focussed ion beam (FIB).

BSE and EBSD measurements of 7d hydrated alite
A 7d hydrated alite (C3S) was embedded, mechanically polished and finally cleaned using an Argon broad ion beam device. This specimen was then imaged using an SEM (Helios G4 UX by Thermo Fisher Scientific) at overlapping positions. The locations of the EBSD measurements relative to the BSE data are illustrated…
High-resolution FIB-SEM dataset of dense inner C-S-H of 28 days hydrated alite
This dataset contains 2 image stacks depicting 28 days hydrated alite (C3S). The volumes were created using a scanning electron microsope (SEM) in backscatter electron mode (BSE), combined with a focussed ion beam (FIB).
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…
Synchrotron X-ray nano-tomography datasets of unhydrated and 12, 16 and 20h hydrated tricalcium silicate particles
Reconstructed synchrotron X-ray nano-tomography (PXCT) datasets of unhydrated (0h) and hydrated (12h, 16h, 20 h) tricalcium silicate (C3S) embedded in epoxy resin. The C3S was sieved to a particle size <10 µm. For the hydration, 15 g of C3S was mixed with 45 g filtered, saturated Ca(OH)2-solution and…
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…
