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).

This dataset contains multiple measurements acquired using the following devices: µXRF: Orbis, EDAX/AMETEK SEM: Helios G4 UX, Thermo Fisher Scientific EDX: XMaxN 80 and Ultim Extreme, Oxford NI: Hysitron TS 77 Select with a Berkovich tip, Bruker CM: VK-X3050, Keyence Method size in px pixel size in nm/px…
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).
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…
