We validate the computational prediction that Ca/Si ~ 1 creates significantly stiffer and harder C-S-H than in OPC pastes, with direct consequences for concrete performance and environmental...

These experiments provide direct access to the kinetics associated with hydration mechanisms. Different parameters such as initial clinker composition and initial concentrations of calcium, silica...

Using the Rietveld method, we provide evidence that the presence of non-quantified material is significant in the studied samples of industrial clinker. This material likely affects grindability...

This research highlights the critical role of aluminum and sulfate doping on the reactivity of belite and indicates that by considering relatively simple chemical techniques, the dissolution and...

Besides giving a more refined description of the C‑S‑H gel atomic structure, we have demonstrated that water speciation has a great effect on the strength properties of C‑S‑H nanoparticles. It is...

We propose a new approach to investigate environmental and safety issues for the use of cement as a candidate for immobilizing radioactive waste such as strontium. It is based on first-principle...

Our approach shows that cohesion within cement paste decreases with decreasing water content, specifically at RH<20% and 27°C. This loss of cohesion within the binding phase significantly...

This model of setting couples hydration kinetics and development of mechanical properties, a combination that allows the prediction of setting times in a bottom-up fashion. Our setting model...

These results provide new understanding of how C-S-H structure and properties vary with water content. The proposed mechanisms governing increased stiffness and strength of C-S-H with low water...

This research highlights the impact of chemical modifications, namely the calcium-to-silicon ratio, on specific heat capacity of C-S-H. It also highlights the power of the bottom-up approach being...
