The Durability and Potential of Roman Concrete
TLDR Roman concrete, a technology from ancient times, is still standing today and has not been replicated or improved upon by modern society. Made up of lime, rocks, and volcanic ash, Roman concrete gets stronger over time and could be a more energy-efficient and environmentally-friendly alternative to modern cement.

Roman concrete, known as opus caementicium, is a particular blend that was used by the Romans to create structures that are still standing today, and it is different from modern cement.
04:07
Roman concrete was incredibly durable and didn't crumble over time like modern concrete, and it even got stronger the longer it was in seawater.
05:27
Roman concrete was made up of three components: lime, rocks as an aggregate, and a volcanic ash called Pozolana, which was the key ingredient that made it so durable and strong.
06:47
The unique mixture of Roman concrete in seawater stimulates the creation of a mineral called aluminum tobermorite, which fills in microfissures and makes the structure harder and more solid over time.
08:10
Roman concrete could be a more energy-efficient and environmentally-friendly alternative to modern cement production, and by studying the ancient formula, we may be able to recreate it or even improve upon it.
