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 ...
Water-to-cement ratio influence on low-carbon cements performances
(2019)
Portland Cement (PC) is the most important active ingredient in most of the construction concrete. However, the PC production is associated with a high carbon dioxide release (around 1 ton of CO2 per ton of PC). One approach ...
Alite hydration mechanism in presence of ye’elimite related to BAY cements
(2019-10-08)
One alternative to decrease CO2 emissions from ordinary Portland Cement (OPC) production consists
on the development of a new kind of eco-cements composed by less calcite demanding phases. That is
the case of ...
Synchrotron X-ray pair distribution function analysis of tricalcium silicate pastes
(2019-09-24)
The analysis of nanocrystalline and amorphous components within cement pastes that contain high amounts of crystalline phases is very challenging. Synchrotron powder diffraction jointly with the pair distribution function ...
