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).
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…
