Concrete Science Research Brief: Mesoscale Modeling of Sorption Hysteresis
December 1, 2012

The model quantitatively predicts sorption hysteresis in hardened cement paste. By answering the basic question, “Where is the water?” it paves the way for bottom-up descriptions of diverse...

Concrete Science Research Brief: When Fracture Stems From the Atom
November 1, 2012

We propose a new approach to study fracture properties by molecular simulation valid for both brittle and ductile materials. This research highlights the possibility to understand and engineer the...

Concrete Science Research Brief: Energy Management - City Texture Matters
October 1, 2012

The novel approach leverages Statistical Physics to describe the complexity of cities in terms of molecular structures. This provides city planners and developers with innovative texture...

Concrete Science Research Brief: Quantum Clinker Engineering
October 1, 2012

This research highlights the critical role of the crystal structure of alite and belite on the dissolution energetics. This novel understanding of the dissolution chemistry eventually holds the...

Concrete Science Research Brief: Induction Period in Alite Hydration
August 1, 2012

This research provides new information about the mechanisms that control the decrease in reactivity of alite during the induction period. This information can only be obtained by detailed atomic...

Concrete Science Research Brief: C-S-H Texture From Sorption Isotherms
July 1, 2012

This unique bottom-up approach developed by the CSHub combines information from atomistic and colloidal simulations with the coarse-grained lattice-gas model allowing validation of the cement...

Concrete Science Research Brief: Validating Effects of Cement Paste Composition on Mechanics
June 1, 2012

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...

Concrete Science Research Brief: Visualizing Hydration Products
May 1, 2012

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...

Concrete Science Research Brief: Crystallinity of Cement Clinkers: Application of Rietveld Refinement
April 1, 2012

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...

Concrete Science Research Brief: Aluminum and Sulfate Doped Belite
March 1, 2012

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...
