Ancient lessons: Roman concrete durable, green

By Jim Destefani / June 10, 2013

Drill core of concrete from a 2,000-year-old Roman breakwater consists of pumice (yellowish inclusions), lava and other volcanic crystalline materials (dark and gray spots), and lime (white). Inset: scanning electron micrograph of aluminum tobermorite crystals believed to provide the superior durability and mechanical properties of Roman seawater concrete.
