MIT Team Reverse-Engineers a Curious 2000-Year-Old Roman Technology to Create Modern Material That Heals Its Own Cracks

2,000 years ago, ancient Roman engineers were building structures that have withstood the test of time remarkably well, many of which remain standing today. At the heart of their success lies a mystery: what were the secrets of ancient Roman concrete that made these buildings so durable? Now, MIT researchers are drawing from this curiously [...]
