An international team of researchers from Rice University, the Massachusetts Institute of Technology and Marseille University has used sophisticated computer models to determine how the molecular structure of concrete results in its physical properties.

Rouzbeh Shahsavari, assistant professor of civil and environmental engineering at Rice University, said the computer models used enabled the scientists to perform detailed analyses of the basic molecular structure of concrete, enabling them to better create methods for altering its physical properties. “The heart of concrete is C-S-H – that’s calcium, silicate and…
