Fracture toughness and material thickness
Breakthrough in Clinker Grinding
April 8, 2014

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...

Composition of cement
Improving Concrete Sustainability through Alite and Belite Reactivity
April 7, 2014

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...

Concrete Science Research Brief: Modeling C3S Impurities Using Cluster Expansion
March 18, 2014

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...

Graph of resilience at high temperatures
Concrete Science Research Brief: Resilience at High Temperatures
January 13, 2014

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....

Concrete Science Research Brief: Early Hydration: A Local Business
November 1, 2013

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...

Concrete Science Research Brief: Controlling the Reactivity of Fly Ash
August 15, 2013

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...

Degree of Hydration
Concrete Science Research Brief: Early Age Fracture Resistance
June 1, 2013

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

Creep
Concrete Science Research Brief: Nano-Engineering Creep
May 1, 2013

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...

Concrete Science Research Brief: Clinker Grindability - Microstructure Matters
April 1, 2013

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...

Concrete Science Research Brief: Predicting C-S-H Aging
March 1, 2013

This is the first time that rigidity theory has been applied to such a complex material. Importing glass science tools to C-S-H brings new ideas to predict the effect of composition on cement...
