Applying glass science tools to cement provides new insights into the relationship between nanoscale composition and macroscopic properties. Our analysis predicts a family of compositions at which...

Particle size reduction is one of the most energy intensive and inefficient processes in use today. Traditional means for calculating energy requirements used for sizing equipment rely on...

Calcium silicate phases, alite and belite, are among the main components of modern portland cements. Alite reacts relatively rapidly with water and is responsible for most of the early strength...

This is the first study where very accurate DFT (Density Functional Theory) calculations are applied to large supercells of clinker using the cluster expansion method. Simulations can be carried...

These calculations on C-S-H resilience provide insight toward damage mechanisms in concrete at high temperatures (e.g., fire environments) that precede polymerization of silica chains....

A new reaction zone hypothesis reconciles a number of experimental observations on the early hydration kinetics of cement. The new MBK simulation model provides a tool for exploring the...

The significance of structure and composition has been displayed in the context of cementitious additives including fly ash and slag. This work has provided a “formula” for model additives to...

Bringing together the correct recipe of experiments (scratching, splitting and calorimetry), the relationships between these mechanical properties and hydration degree were determined. More...

We have shown that the multi-scale logarithmic creep can be predicted from direct simulations at fundamental scales. This lays the groundwork for an unprecedented understanding of the mechanisms...

This multi-scale investigation of fracture properties with the microscratch test highlights the importance of microstructure in clinker grindability. This original approach also provides a means...
