Ancient Roman concrete has shown remarkable durability, with structures like the Pantheon remaining intact for nearly 2,000 years. Recent research suggests that this ancient concrete may have had self-healing properties, allowing it to fill its own cracks through a process involving calcium deposits. Scientists analyzed mortar samples from the ancient city of Privernum and discovered that the Romans used a reactive form of limestone, quicklime, which facilitated chemical reactions that generated heat and created these deposits. This discovery not only sheds light on Roman engineering techniques but also offers insights for enhancing modern concrete, potentially leading to longer-lasting infrastructures and reduced greenhouse gas emissions from cement production.
