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.”
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.
I thought we do know the depth of the bunkers though. And that American bombs can’t go that deep, even multiple of them
I can’t speak to that aspect. But I firmly believe that if our military planned and carried out this strike, then we had very good evidence that their bunkers were at a depth these ordinance could reach.
Consider who actually makes this decision, in this case. It’s highly likely our intelligence assessment here is very accurate orr flat out denied by the dipshits actually making the call if it’s not what they want to hear.
Like they did publicly. On this conflict. To the press.
Why would we bother with that level of analysis just to distract people from ICE raids?
That concrete really isn’t new and really isn’t that special. There’s a reason they built it under a mountain - because the mountain does what concrete can’t.
From this article it sounds very likely that the bunker buster attack failed.
I mean they usually only do about 30 damage anyways.
So Iran knew EXACTLY how strong they needed to make their defenses!
Pretty stupid of the American military to give that info to a game developer, that would obviously use it.I love how unhinged random fan wikis sound without context. Here for instance: Bunker Buster, see also: Concrete Donkey and Buffalo of Lies
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.
Impressive.
If it’s reinforced steel concrete, it would be much harder to bunker bust.
They mean mixing in steel dust or nylon hair?
Hard to believe this is a recent enough thought.
It’s been done in mining for decades
I asked because I’ve heard such advice for bloody countryside home floors. Not even something requiring it.
Turns out that anti-cracking tech is widely applicable, if a bit expensive.
Its called FiberMesh
Fiberglass, carbon fibers, or small steel wires. They don’t need to be long, the snippets are only a few centimeters in the video I have seen.
I low key assume this means the next strike will be using tactical nukes. This is bad news folks.
…please don’t give them ideas.
Just one followup question: Who cares?
Edit:
Trump didn’t give the order to specifically destroy the bunkers
Had that order been given they would have continuously bombed the site(s) until it/they was/were destroyed
Judging by the results of the strike the order seems to be very limited
