Roman concrete has often been revered for its durability but why exactly is it so much better than modern concrete? It appears to have magical abilities that allow it to self-heal cracks, make it resistant to sea water and allow it to become stronger over time. A series of recent studies have shed light on this and revealed that Roman concrete's durability is connected with its ingredients and how the environment reacted to it over time.

And you'll be better for it
Congratulations Gareth on getting a sponsor! I have greatly enjoyed your videos for over a year, and I hope your channel continues to have success.
Thanks so much!
We are so technologically advanced, that we can figure out what people already knew thousands of years ago. 🤔
Yep, it's all bureaucracy and PR
We can’t even get back to the moon
(-;
@@greggstrasser5791 Yeah but thousands of years ago, they were not blessed with the genius who came up with built in obsolescence.
@@amywas1 There is a difference between built in obsolescence and design life.

Our Lord and Savior, Elon Musk has reusable rockets! 🙄
There is at least one modern factor that is overlooked here.
It is not corrosion, but corruption. I know that modern asphalt is designed to fail. So with concrete. Job security is the name of the modern game.
Gareth, you are the only guy I know who could get me to sit through a lecture on concrete lol 😄
The Geopolymer Institute reverse engineered the Egyptian and South American artificial stone also. The pillow like walls in Puma Punku and the H shaped blocks were made from artificial stone. As well as many limestone blocks on the great pyramid. Apparently the magnetic field is preserved when the stone is formed, testing on many stones on the great pyramid have shown that they're all oriented to the cardinal points. Impossible to do unless they were formed in place.
Topics like this are of much greater interest to me than the holes in mainstream physics. Thank you.
best explanation of Roman concrete that I've come across.
Great to hear about your channel having a sponsor; hope I'll see more subs as this channel deserves.
Absolutely brilliant video
Interesting video about something outside the plate once in a while.
BTW, congrats on your sponsorship.👍
I build pools so I’m always around concrete. Fascinating video.
To conclude romans had:
-little frost
-structures which in stead of strong concrete and rebar use arches and huge amounts of weaker material to reduce tensile stress and corresponding cracks
- months to wait for the concrete to harden
- buildings which if they collapse, do so without warning
Perhaps the key here is architectural beauty rather than skyward monstrosities. A project test would be to build coastal accommodation that would not be blown away by the big bad wolf every hurricane season.
To me the biggest mystery is how such an amzingly advanced and useful technology was completely forgotten again for 1900 years.
Make Concrete Great Again!
Great video, but I still don't know why we can't make better concrete.
Capitalism
Okay, this is one of my historical anger subjects: The recipe, logic and reasoning has been published and available for over 1000 years and taught in universities around the world. It's in "De Archetectura" by Vitruvius.
He tells you exactly how to mix it and why and how to make different mixes for different purposes and dependant on whether or not there is sea exposure.
Roman concrete, to me, is the perfect example of how we disrespect ancient passed-down knowledge because we think we're so smart and we know everything.
I still don't get if the recipe was or wasn't known to us. Why researchers struggled, if the info was available from Vitruvius?
Fascinating.
Reminds me of the work Land of Chem is doing in Egypt with the pyramids
good video, would like more stuff like this.
There's no comparison. There's Roman roads still fine for use today 2,000 years later. I got grass growing up between the cracks on my street, and its a myriad of "patched potholes". Where the patches last 6 months maybe before needing to repair the potholes again. No wonder everyone is buying SUV's, you need them on American roads! Hell, dirt or sand would probably be better than American concrete roads. Or is it only in Ohio the roads suck?
That is fascinating. Congratulations on your sponsor! While I enjoy what you do, I didn't expect you to get sponsored by anyone exactly because your content goes against the grain most of the time.
Thanks 😊 I was pleasantly surprised when they reached out but I felt it was a match. Not sure it will be a regular thing but I wanted to explore what it involved
@@SeethePattern Yea, this topic matches your content well. Hopefully there'll be more of this in the future, as we're living in exciting times I think.
@@SeethePattern Sponsors supporting teaching and learning effectively? Great sponsor. I suppose it's been my learning pattern for my years. Many skip or obsess. They can't get the point, and so they never find where to dive. At very least the platform you are promoting teaches that one must survey the waters before diving, and dive before burdening, possessing and so being possessed by. Dating works like this. I suppose then it must be a kind of Fractal Thing?
Patreon really didn't think enough about what benefactors would be called when thanked by their beneficiaries.
Veritasium recently did a video dedicated to dismissing Roman concrete (the guy is enormously popular which means factually, he has sold his soul). His argument boils down to, Roman concrete lasting thousands of years is not superior to modern portland concrete expected to last less than one hundred years because reasons.
he even stated that Roman concrete traits stemmed from poor mixing of the materials!
I dont care for his contents, but I remember watching his video about the pyramids and show himself next to that unfinished 1000-ton granite obelisk on the ground and said people create the surrounding trench by smashing dolerite rock against the granite.
@@erikahuxley which is what i mean by him selling his soul. He own publishes what he is allowed to publish
Never forget , human history is deliberately erased and invented . A grand cover up. Which is very sinister
Thanks for the video. It's nice to know that the Romans were smarter than we are today. And modern man is too dumb to reverse engineer the Roman concrete and make use of it today instead of the garbage we're (the taxpayers) all stuck with. It's embarrassing really.
BUT SOMEHOW AFTER ROME...AND IT'S GONE
look up Joseph davidovits recreation of egyptian/greek concrete aka man made stone. Roman concrete probably is sophistication of older recipes.
they also found terrazzo at Gobekli tepe and karahan tepe.
Very interesting, thank you. Have you looked into American Rock Cement, which was used to construct much of the early great American architecture, and which shares many of the qualities of Roman cement. PM me if you want to know more. Cheers!
could you imagine if our highways were made of this stuff.
Great job, I think the planets environment was different back then as well. There can only be one reason why tech like this is lost to us today.,,,thx.
I'm gonna need some Romans to come over and repour my driveway.
Have You Seen Hempcrete?
C.E.?
Come on, man.
I think the Romans learned how to use concrete from the Egyptians. I bet the Pyramids were constructed using that technology.
Unlikely, as these cultures are separated by a large time gap (thousands of years). In addition, the pyramids were built from blocks of cut granite and other stones. The cutting technology used is not entirely clear, although, judging by the traces of stoneworking, more sophisticated tools than modern ones were used.
The Egyptian/'Minoan' was the previous massive Empire to Rome. I'm sure people will say the Macedonian or the Persians, but Egypt, like America today, used a vast amount of soft power. Here is not the place to deal with that, but: I'm sure Rome learned as much from 'Egypt' as we have from Rome. Fools will think nothing. But some know.
@@naujadiena Cut granite is the mainstream theory. But I don't buy that. That the Egyptians learned how to use concrete is much plausible explanation in my opinion. Way simpler than how they cut the stones and then moved them hundreds of kilometers and lifted them in place.
@@asdf3568 it is likely a geopolymer (though I have no idea why they sculpted granite like clay at the same time), but Roman concrete is significantly different from that.
For more details, think about the gigantic sarcophagi that are optically flat and polish black, and fused. The vandalism on it implies a technology that can sculpt rocks.
@@asdf3568 The fact is that there are signs of stone cutting. And the main theory is to completely ignore this question... or invent some theories not based on facts. Also, as far back as antiquity, and even ancient Egypt, the great pyramids were long forgotten history, as was the culture that built them.
Most of Rome isn't even 1000 years old. Before that was the old empire scavenged and erased by Europe's royals.
That's good news!
Fantastic.
Geopolymers!
One thing they should do with modern concrete is start coating or galvanizing dipping in Zink the steel rebar which makes the zinka sacrificial anode so the rebar won't rust I don't know why they don't do that once the Ingress of water happens the rebar rusts what makes the rebar expand in diameter which makes the concrete break faster very interesting documentary I agree modern concrete is severely lacking
They could coat it in zamack, and call it a day
There is a chance that you are going to be asked to develop a new concrete company. This information has been coming out for years, and I suspect we've always had it to some degree (or better, see the history of 'sculpture', especially Italian). But you present this so well that I'm sure many will become sold on the idea of less planned-obsolescence, an idea whose time had once come, but is now waning for a small spectrum of reasons.
That would be pretty neat, in that they spent the most expensive concretes, a geopolymer, on fancy sculptures.
@@Dan-gs3kg Geopolymers aren't considered as a normal part of organic chemistry, right? Do you think that perhaps carbons played a role at some point? Just a question, not intending to lead. This is absolutely not me field. "Me's" . :)
To clarify, at some chemically processing point. And it really is a question. I suppose if it were partially organo-, there would be somewhere traces. [Which we know that in mineral crystalline structures chemical reactions proceed slowly, but directional certain.]
@@Dan-gs3kg I suppose I should say that polymers keep seeming to be something, no? Confusing to me /:
@@OrpheoTreshula not sure what you are going on about, I know that a group was able to replicate limestone geopolymers seen in the pyramids. But then we get into the odd question of why did they sculpt granite for the boelisks.
Ash, ash ... baby ....

3:25 That's not how the Romans constructed roads
British labor laws require wearing a hardhat, while making this video!
I guarantee that if we forensically looked at the evolution here, we will find that the so-called “Roman concrete” wasn’t even Roman.
We should always remember that history will provide the evidence that Romans have good swords, and good abilities to conquer people. Everything else likely came from somewhere else.
Romans = HYJACKED Tartarian technology from our 5D Earth realm (post Atlantis/Lemurian)… Thanks for this video - just subscribed 😻😻😻
It's not that today's concrete HAS to be inferior. It's just that men today are inferior.
Someone in Cuba has made superior concrete, check it out.
And search terms to help look for that?
Once again I plead with you to disable google translate, the title is complete nonsense, I had to stare at it for a minute to figure out what it even was trying to say.
"Why is our concrete so poor...", in a word: capitalism. The advent of the modern concrete process is a cost-based product (just like everything else, in this modern World), & the Portland cement manufacturing process itself is no different. It would be inherently expensive to manufacture buildings that lasted beyond the present required timeframes, so inferior, compromised ingredients are utilised. And, building Standards are designed around these compromises (they are regulated around the fact this modern cement, & concrete only endures so long, dependent on location, & conditions).
Pantheon, Rome was built before Christ ? And modern concrete last 50 years in better conditions 200 years. Even with all magical properties of ancient Roman concrete none man made structure can last 2000 years, mixture of volcanic ash, entropy still present. And yeah Pantheon, Rome is modern building and all ancient buildings are recent 17 - 19 century building with attached history later by historians. As one historians why Greco/roman history produced 700 vey famous Greek philosophers and mathematicians and all mighty Roman later Hellenistic culture inheritors produced only one Cicero which was not philosopher not mathematician but politician :) Roman tool Latin language from Latin tribe but historians say Latin people be genocide by romans but where precise location we don't know. Romanian made movie Dacii (The Dacians) in 1966 :))) Even Dacians are not Romanians :))) It feels everything that is ancient feels very recent events.
Well that was a long ad
Roman concrete hype is pure myth. They were designed for only compressive loads which our modern concrete does far, far better at. The hoover dam is almost 100 years old and is designed to last 2,000 years (estimated over 10,000). High rise buildings are thin skeletal structures vs roman buildings which use arch and other compressive construction which means far heavier and thicker material. They were also build on solid rock foundation vs soft soil/sand as many buildings are today. Has nothing to do with the material but the construction method.
Interesting! Do you have more resources on your take? I'd love to look at your sources, or if this is largely by your experience, to hear more.
At this point, the self-healing ability of roman concrete is pretty well documented, and is evident regardless of construction method. As for modern concrete, you only have to look around to draw conclusions of its longevity.
I would say that as an engineer, you would know that materials are designed for their intended job. Doesn't it seem to you that the Romans excellently designed their concrete for their intended purposes, and sometimes in ways that are a bit novel to us?
@@OrpheoTreshula I was a field engineer for a high rise concrete company. Lots of videos on RUclips that explain it. It's common sense though it's weird when people ask for sources on something so obvious
@@OrpheoTreshula no. Romans would dream of constructing high rise structures we have now. No one wants a house with 4 feet wide walls
I pay RUclips not to have commercials. I see the merch under the description: Can't you just put the Blinkist ad in the descriptions ? : isn't that enough imposition? Unsubscribed.
hi how can i contact you via email?
It’s in the description
