Their \u201cback to the future\u201d findings could help reduce the environmental impact of cement production in today\u2019s society.<\/p>\n\n\n\n<p>The ancient Romans were masters of engineering, building a huge network of roads, aqueducts, ports, and temples \u2014 many of which still stand to this very day! Many of these structures were built with concrete, including Rome\u2019s Pantheon, which has the world\u2019s largest unreinforced concrete dome and is still intact despite being dedicated&nbsp;<a rel=\"noreferrer noopener\" href=\"https:\/\/studyfinds.org\/category\/historical\/\" target=\"_blank\">in the year 128 AD<\/a>. Some ancient Roman aqueducts still deliver water to the Eternal City today, while many modern concrete structures crumble after just a few decades.<\/p>\n\n\n\n<p>Scientists have spent decades trying to figure out the secret of the \u201cultra-durable\u201d construction material, particularly in structures that endured especially harsh conditions \u2014 such as docks, sewers, and seawalls.<\/p>\n\n\n\n<p>Now, an international team has discovered ancient concrete-manufacturing techniques that incorporated several key \u201cself-healing\u201d properties. For years, researchers believed the key to the ancient concrete\u2019s durability was one ingredient: pozzolanic material, such as volcanic ash from the area of Pozzuoli, on the Bay of Naples.<\/p>\n\n\n\n<p>[ <a href=\"https:\/\/studyfinds.org\/why-was-roman-concrete-durable\/\" target=\"_blank\" rel=\"noreferrer noopener\">click to continue reading at Study Finds<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from Study Finds How has ancient Roman cement stood test of time so well?
