Hunt became the 14th victim of the flood when his truck was swept off of a Route H bridge into the Pomme de Terre River the day after Christmas in 2016. [Read more…]

Dr. Mohamed ElGawady, associate professor of civil, architectural and environmental engineering at Missouri S&T, is testing mixtures of concrete made with fly ash that can be more durable, strong and resilient than concrete using ordinary Portland cement (OPC). [Read more…]
