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 ...

Ptychographic X-ray computed tomography provides 3D electron mass density and attenuationcoefficient distributions of unaltered cement pastes with an isotropic resolution below 100 nm. Thisimaging technique allows ...

The identification and quantification of amorphous components and nanocrystalline phases with very small crystal sizes, smaller than ~3 nm, within samples containing crystalline phases is very challenging. However, this ...

The characterization of the nanocrystalline/amorphous materials is very challenging but the presence of these materials mixed with large amounts of crystalline phases makes the analysis even more complicated. This is the ...

Oil and gas well cements are multimineral materials that hydrate under high pressure and temperature. Their overall reactivity at early ages is studied by a number of techniques including through the use of the consistometer. ...

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 ...

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 ...

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 ...

Los materiales de construcción son componentes complejos de gran interés comercial. Por ello, el conocimiento cuantitativo de su mineralogía a través de la difracción de rayos X (DRX) es de crucial importancia para optimizar ...
