AB LC3 type cements do not need introduction in this conference, neither the importance of studying themicroporosity features (amount, size(s), connectivities, etc.). However, analysing the porosity in anaccurate, quantitative and robust way is far from easy/well-established. Here, we intend to contributeby analysing selected microporosity features and their evolution using synchrotron (and laboratory) X-ray microtomography (μCT) with the final goal of gaining a deeper insight into the microstructures ofLC3 binders. Nowadays, synchrotron μCT allows obtaining tomograms in binders with voxel sizes of 0.3μm and true spatial resolution close to 1.0 μm [1]. Additionally, for this work, the detector was placedat 5.5 mm from the samples and therefore, phase-propagation increased the visibility betweencomponents with similar attenuations to the X-rays. The Paganin phase retrieval algorithm [2] wasemployed which resulted in augmented contrast. Moreover, another advantage is that fast acquisitiontimes are possible, i.e. a full high-resolution tomogram can be recorded in 5 minutes.
