Did You Know? Italy

Many modern concrete structures begin to deteriorate after several decades.

Some Roman structures built with ancient concrete have remained standing for nearly 2,000 years.

Scientists discovered that Roman builders mixed volcanic ash with lime and seawater, creating a material that actually became stronger over time as minerals formed inside tiny cracks.

This remarkable recipe helped preserve harbors, temples, and aqueducts that continue to amaze engineers today.
