Previously, a yield strength of 5,000 pounds per square inch (psi) was enough for concrete to be rated as “high strength,” with the best going up to 10,000 psi. The new UHPC can withstand 40,000 psi or more.
The greater strength is achieved by turning concrete into a composite material with the addition of steel or other fibers. These fibers hold the concrete together and prevent cracks from spreading throughout it, negating the brittleness. “Instead of getting a few large cracks in a concrete panel, you get lots of smaller cracks,” says Barnett. “The fibers give it more fracture energy.”
I sure would like to read this article, it seems fascinating, but it's paywalled.

Hardly. Did you read the article?

Fiber reinforcment is thousands of years old.

They used nagarjuna cement

Nothing is unbreakable.

Ha ha yea go iran! Fuck the west and their imperialist bull!

From this article it sounds very likely that the bunker buster attack failed.
And I read that the US used more than half of its stock of these bunker-buster bombs in this attack, the largest conventional bunker-busters in existence. So they can't simply try again.

So I did not read the article because of a paywall I'm too lazy to circumvent right now
But from OP's summary, the main technology they're talking about is concrete reinforced with steel or other fibers.
And that's definitely more advanced than "pyramid age"
But it's also pretty much a direct descendant of mud brick reinforced with straw which humanity has been using since well before the pyramids. Same basic concept, different materials.
So yes and no.

I mean they usually only do about 30 damage anyways.

I low key assume this means the next strike will be using tactical nukes. This is bad news folks.

Calling that pyramid age I think is a little disingenuous, they didn’t have 40,000 psi concrete back in those days.

You can't break what is already broken

Someone, somewhere, said they don't like you.
Now CRY!

Yes....no.....maybe? I don't know. Can you repeat the question?

Holy nothing burger, Batman!
First off, this article is from 2022, re-released to farm clicks from the current hype cycle.
Secondly, this is conjecture on top of conjecture. They discuss that we can't know the current damage from satellite, and Iran down plays the damage. Then they go on to say "concrete is strong and can be stronger".
Articles like this annoy me. It's all based on lots of unsubstantiated claims, and then one guy's theoretical research. We don't know the strength of the bombs. We don't know the strength of Iran's bunkers. We don't know how much damage was done. None of this has changed. I doubt we'll ever really know. But throw whatever political spin on it you want, and now you've got a click worthy news article.

That's what they want you to think, but we have no evidence to either direction. And I doubt we will ever have a definitive answer.
