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

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.

What material would that be? Corrosives have limits, they can't just keep dissolving stuff forever.

And what would "total failure" look like? It's a mountain, it's not going to just collapse into goo.

I mean they usually only do about 30 damage anyways.

My first thought is actually getting the corrosive substance onto enough of the concrete would be difficult, assuming they aren’t able to penetrate the concrete then they have to rely on it seeping from the ground, or if they can penetrate then the substance is only really going to be in the chamber where the buster detonated.

I have zero experience with ordnance or busting bunkers though so that’s just a shot in the dark

There's also the fact that the majority of Iran's nuclear facilities were built before UHPC, the concrete discussed in the article, was available!

I thought we do know the depth of the bunkers though. And that American bombs can’t go that deep, even multiple of them

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.”

Egyptians stacked blocks of stone to build the pyramids.

Roman concrete was impressively strong.

Neither of them had steel-reinforced concrete.

Neither did Gothic cathedrals, which is why they needed flying buttresses.

Reinforced concrete as we know it today is a 19th century innovation, as I understand it.

Maybe the commenter was thinking of adobe.

Sounds to me like someone is trying to justify actually using a tactical, atomic bunker buster.

From this article it sounds very likely that the bunker buster attack failed.

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.

Giving the yield strength in psi is the most pointless thing ever. Every single engineer would use metric Pa so its clearly a conversion for the average american idiot but the average American idiot has no idea what yield strength is.

I love how unhinged random fan wikis sound without context. Here for instance: Bunker Buster, see also: Concrete Donkey and Buffalo of Lies
