Dr. Dimitri Feys, a professor at Missouri S&T, is studying ways to make self-consolidating concrete suitable for bridge building and other construction projects. He says the main use of this concrete is in Japan and Europe, and it slowly is making its way in the U.S. market.

One of the challenges, Feys says, is figuring out a way to keep the concrete homogenous throughout the produced structural element. The goal is to keep the gravel from sinking to the bottom as the concrete flows through the form so that it doesn't negatively affect the finished product's quality in strength and durability.

The ultimate goal is to make self-consolidating concrete a common product used in the U.S., he says.

The project is funded by the U.S. Department of Transportation through the Research on Concrete Applications for Sustainable Transportation (RE-CAST) consortium, in which Missouri S&T partners with Rutgers University, Southern University, the University of Illinois at Urbana-Champaign and the University of Miami.
