Neglect a modern concrete structure for a few decades and it’ll start to fall apart – and yet, structures built by the ancient Romans are still standing strong after 2,000 years. Now, engineers have ...

Scientists have long pondered the durability of ancient Roman concrete structures, which have not only stood the test of time but have held up under extreme conditions, assuming it came down to a ...

Evidence of Roman engineering ingenuity is not in short supply. From Rome’s Pantheon to the Pont du Gard aqueduct in southern France to the Alcántara Bridge on the Iberian Peninsula, large-scale ...

Is there a significant survivor bias in analyzing surviving Roman concrete structures? Perhaps a very high percentage of Roman concrete structures fell apart after a few years. Are we just analyzing ...

A rare mineral that has allowed Roman concrete marine barriers to survive for more than 2,000 years has been found in the thick concrete walls of a decommissioned nuclear power plant in Japan. The ...

In a list of walls that you’d want to stay strong, those in a nuclear reactor would be near the top. Now, researchers have found that the walls in a decommissioned power plant in Japan have not only ...
