The Last Word: UTA’s Warda Ashraf on Developing Eco‑Friendly Concrete Based on an Ancient Roman Recipe

Ashraf was quoted in a recent New York Times article, "Reinventing Concrete, the Ancient Roman Way," about using 2,000-year-old Roman secrets to create concrete for underwater use in bridges, breakwaters, and artificial reefs.
