MechSE group creating stronger building materials

Science Daily (Nov. 21) -- During the 69th Annual Meeting of the American Physical Society’s Division of Fluid Dynamics, MechSE assistant professor Randy Ewoldt and MechSE doctoral candidate Jeremy Koch presented their work exploring how air bubbles rise within a complex fluid, like those found while processing wet concrete, wondered if they could actually get them to sink instead by shaking the mixture in the right way. The finding may pave the way for stronger building materials by helping remove large air voids from wet concrete, the authors say. Also: Cosmos (Nov. 24), Science (Nov. 29).
