New Study Reveals Rome’s Eco-Friendly Construction
As well as being just as durable, Roman concrete was also more eco-friendly than our modern recipe, which consists of lime and clay. This mixture requires that it be heated at high temperatures and results in significant carbon dioxide emissions. Roman hydraulic concrete, on the other hand, was made from pumice, mortar, lime and volcanic ash from Italy—pozzolana—and fired at much lower temperatures, thereby creating the more eco-friendly Roman concrete. While it takes longer for the Roman concrete to set, it is just as durable as modern concrete. A full report of Monteiro’s findings was posted online in the Journal of the American Ceramic Society on May 28.

This summer, the Jezreel Valley Regional Project teamed up with Israeli archaeologist Yotam Tepper to expose a Roman camp just south of Tel Megiddo known as Legio. In a web-exclusive report, directors Matthew J. Adams, Jonathan David and Yotam Tepper describe the first archaeological investigation of a second-century C.E. Roman camp in the Eastern Roman Empire.
