Riddle solved: Why was Roman concrete so durable?
The ancient Romans were masters of engineering, constructing vast networks of roads, aqueducts, ports, and massive buildings, whose remains have survived for two millennia. Many of these structures were built with concrete: Rome's famed Pantheon, which has the world's largest unreinforced concrete d...

Great exciting discovery. Also it seems the researchers are trying to patent it - isn’t the prior art 2000 years old though?
“Previously disregarded as merely evidence of sloppy mixing practices, or poor-quality raw materials, the new study suggests that these tiny lime clasts gave the concrete a previously unrecognized self-healing capability. "The idea that the presence of these lime clasts was simply attributed to low quality control always bothered me," says Masic. "If the Romans put so much effort into making an outstanding construction material, following all of the detailed recipes that had been optimized over the course of many centuries, why would they put so little effort into ensuring the production of a well-mixed final product? There has to be more to this story."”
