The concrete released less CO2 into the atmosphere than any of its modern counterparts. It was also able to self repair any cracks that occurred, making it an incredibly durable material.
The process to make this concrete stumped historians so much that it wasn’t until 2013 when UC Berkley published the first article detailing the process of making Roman concrete.
