Concrete has long been one of the world's most important building materials as well as one the most durable and with the amount of concrete that wil be necessary for the future, it is imperative that scientists learn as much about it as possible. The MIT-led team researched concrete with the goal of "doing more with less."
In order to address the most important issue wihich is the binding of concrete, the team looked at cement hydrate on a nano-scale as they had done in the past, with the goal of applying it on a macro-level:
In 2009, Pellenq, Ulm, and an international group of researchers associated with CSHub published the first description of cement hydrate's three-dimensional molecular structure. Subsequently, they determined a new formula that yields cement hydrate particles in which the atoms occur in a specific configuration—a "sweet spot"—that increases particle strength by 50 percent.
