Engineers, individuals in the concrete industry, architects, and more have for years stood in awe of the concrete works that make up the historic landscape of Rome. How have these concrete works stood the test of time for two millennia? 

The answer to this question could be discovered by new research out of the University of California Berkley. Dr. Marie Jackson of the UCB civil and environmental engineering department, with a team, has looked into understanding how these Roman concrete structures have withstood the test of time. The answer? Volcanic ash from a nearby volcano. The Pozzolanic cement derives from the volcano Pozzolane Rosse where ash flowed half a million years ago just 12 miles southeast of Rome. 

A team went to recreate this specific cement mix and found that this particular cement mix had better strength and longevity than most cement.
