Pompeii Study Challenges Roman Concrete Understanding

Scientists from MIT studied old buildings in Pompeii and found that Roman concrete was made in a special way.

They discovered that the Romans mixed lime with volcanic ash and other dry stuff before adding water.

This created a chemical reaction that made the concrete strong and able to fix small cracks over time.

This is different from what an ancient writer named Vitruvius wrote.

The researchers think the Romans used a more advanced method than what was described in old texts.

This discovery is important because modern engineers want to make concrete that can heal itself, just like the Roman concrete did.
