A fascinating look at how ancient Roman concrete was created and how it had properties that even modern cement does not have. We'll look into monumental structures, aqueducts and under water architecture. Note: This was originally a YouTube Members only video, but not all members only videos on YouTube are being mirrored here on Patreon and this applies retroactively. But this isn't just a re upload, it's a remaster, meaning that I've touched up contrast and color correction and added an intro, extra commentary not available in the version on YouTube and a new ending with questions specifically for you. I hope you enjoy.

I lament that we as a species do not seem to value accrued applied knowledge the same way as scientifically attained knowledge. As a homeowner I would gladly take Roman Concrete and utilize it in the construction of my home, maybe improving upon it with rebar reinforcement? Unless the rebar itself changes the chemical make up of the mix post construction? If you find this interesting you might look into the rediscovery of ancient hemprete construction found in ruined palaces of India and homes of France.

I’m thinking rebar of any kind would have to be marine grade stainless steel, or it would rust. But it is a good idea.

Can't recall if it was an engineer or a contractor that told me this...there are two types of concrete. 1. Concrete that has cracked and 2. Concrete that will crack.

I have seen the Pantheon it is a great example of the durability of Roman concrete. My daily thought about the Roman empire no less lol.

Thank you. You always delve into topics I never thought would interest me. But it always does. 🙂

I read or heard that modern concrete is quick drying to speed construction, but is consequently much less sturdy, lasting between ten and fifty years maximum. It's said, however, that the concrete in Hoover Dam is still curing, nearly a century later. Frankly, it's a reflection of values about which type a society uses. Capitalism depends upon obsolescence, but the Romans built to last because they didn't want to have rebuild it again. Again, social values reflected in their infrastructure. I prefer the Roman attitude. But that's my not-so-humble opinion. Slainté (Irish for "to your health!")

I love anything and everything Ancient Rome (and Greece for that matter)
