Accuracy in Cement Hydration Investigations: Combined X-ray Microtomography and Powder Diffraction Analyses
(MDPI, 2021-11-17)Cement hydration is a very complex set of processes. The evolution of the crystalline phases during hydration can be accurately followed by X-ray powder diffraction data evaluated by the Rietveld method. However, accurate ... -
Limestone calcined clay binders based on a Belite-rich cement
(Elsevier, 2023)Portland-based Limestone Calcined Clay Cements, LC3, are receiving considerable attention because the CO2 footprint can be reduced up to 40 %. Here, we report a related family: Belite-rich-LC3. These blends are expected ... -
Phase and microstructure evolutions in LC3 binders by multi-technique approach including synchrotron microtomography
(Elsevier, 2021-06-19)Limestone Calcined Clay Cements, LC3, are attracting a lot of attention as it is possible to reduce the clinker factor by 50%, which means a cement CO2 footprint reduction of 40%. This is compatible with maintaining the ... -
Quantitative disentanglement of nanocrystalline phases in cement pastes by synchrotron ptychographic X-ray tomography
(IUCr, 2019)Mortars and concretes are ubiquitous materials with very complex hierarchical microstructures. To fully understand their main properties and to decrease their CO2 footprint, a sound description of their spatially resolved ...
