Despite a century of research, our understanding of cement dissolution and precipitation processes at early ages is very limited. This is due to the lack of methods that can image these processes with enough spatial ...

The use of supplementary cementitious materials is currently the most favorable strategy for reducing CO2 emissions in cements. Limestone Calcined Clay Cements, LC3, are a type of cement that allows the reduction of CO2 ...

Portland-based Limestone Calcined Clay Cements (LC3) are attracting a lot of the attention from scholars and field applications due to the reduction in CO2 emissions. However, their low mechanical strengths at early ages ...

Hydration of Portland cements (PC) is a complex phenomenon caused by the presence of multiple components with multi-length scale variability. To investigate this complicated process, state-of-theart 3D nanoimaging ...

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 ...

There are many commercially important multiphase materials which contain amorphous phases, such as cement pastes, porcelains, glass-ceramics or pharmaceutical compounds. However, the analysis of amorphous phase(s) within ...

Building materials have complex hierarchical microstructures. The largest components are coarse aggregates with dimensions larger than a few centimetres and the smallest ones are the calcium silicate hydrate (C-S-H) gel ...

The main aim of this study is to apply synchrotron radiation techniques for the study of hydrated cement pastes. In particular, the tetracalcium aluminoferrite phase, C4AF in cement nomenclature, is the major iron-containing ...

This study explores the feasibility of using calcined bentonitic clays in LC3-50 binders. Four commercially available bentonite rocks were thermally activated and milled to a Dv,50 of 12 ± 2 μm. Their pozzolanic activities ...
