Into the void: Random gaps and particles work together to play key role in concrete’s strength

By Stephanie Liverani / August 9, 2016

Rice University researchers (Houston, Texas) want to know what makes concrete stronger and tougher. And after analyzing more than 600 computer models of concrete’s inner matrix, they determined that both voids and particles are key players in giving the material its remarkable qualities.

Display of self-interlocking elements from oxide ceramics. Assemblies of such elements possess an increased bending compliance compared to bulk plates. Cracks are confined to a few elements, so that most of the elements stay intact and are reusable. Credit: T. Krause et al.; Adv. Eng. Mater. For many high-temperature applications, ceramics are indispensable. No other…
