Researchers still puzzle over how Roman concrete was made, but they have a few clues, including many of its ingredients and that it is self-healing.
Modern concrete begins with cement, which is a fine powder that turns into a paste when mixed with water.
The Maya in Mesoamerica around 1100 B.C. developed concrete precursors using quicklime , which results from limestone heated to high temperatures.
Portland cement doesn't permit the formation of lime clasts in its mixing process.
The Romans likely hot mixed quicklime, ash, and water, the clasts remained "as small inclusions in the cement," Dicus said.
"This is 2,000 years old , and it is just as hard as the day it was poured".
