How Did Roman Concrete Last 2,000 Years

Описание: The Pantheon's dome has stood for nearly 2,000 years without repair. Modern concrete structures crumble in decades. Scientists have finally discovered why. In this video, we reconstruct the secrets of Roman concrete - from the volcanic ash that made it possible to the seawater that made it stronger. See how this ancient material built the largest unreinforced dome in history, harbors that survive beneath the sea, and infrastructure that outlasted an empire.

Watch to discover:
• The volcanic ingredient that changed everything
• Why Roman concrete heals itself
• The seawater secret scientists only solved in 2017
• How the Pantheon's dome defies modern engineering
• What we're learning from 2,000-year-old recipes
