If so, the key to the durability of Roman concrete was hot mixing. This, according to Masic, would have reduced the curing and setting time and ultimately allowed a much faster construction.

The outlet said these deposits, described as "lime clasts" and not found in concrete today, were once chalked up to poor mixing practices. But the MIT professor took issue with this line of thought.

Ancient Roman concrete is known as some of the strongest in history, and a new study finally explains why. MIT researchers studied the self-healing properties of the concrete mix. Extreme ...

For years, researchers believed the secret to Roman concrete was the mix of volcanic ash and lime that the ancient Romans used. However, ...

And we just ignored the lime as the key ingredient of a Roman concrete mix. SIMON: Now, you point out that this ancient Roman concrete not only lasts centuries, but it would reduce the carbon ...

The Pantheon in Rome is seen in August 2017. The ancient Romans perfected their concrete mix — one that gets stronger with time — around 30 B.C. (Andreas Solaro/AFP/Getty Images) Is there ...

Use of an ancient Roman concrete-mixing technique called “hot mixing” created blocks that could heal themselves when cracked, according to the paper published in Science Advances.

Researchers examine Roman concrete's self-healing properties, ... Seymour, Linda M. et al. "Hot mixing: Mechanistic insights into the durability of ancient Roman concrete." ...

Roman concrete. The secrets behind Roman concrete come from both its ingredients and the methods for mixing them. One "game changer," according to Dicus, was pozzolan, or ash.

The Roman use of Volcanic ash and the Rock Tuffa which is soft to carve and then hardens. Self healing concrete with graphene re-enforcement will allow for advanced light weight designs.

Concrete is ubiquitous in our modern world, forming the backbone of buildings, bridges, and infrastructure. Its history stretches back millennia, with techniques lost and rediscovered over time ...
