Iran's Invulnerable Bunkers?
A few weeks back, the Air Force detonated out its most powerful bunker-buster yet. But a new Iranian super-strong concrete might make it almost useless before it reaches service.
Ord_massive_ordnance_penetrator_boe I owe this story to DANGER ROOM reader Jay Sappington, a civil engineer in Fort Worth. He graduated with his masters from the University of Texas at Arlington (UTA), where he had participated in a student competition organized by the American Concrete Institute. The challenge was to make a 2?x2? concrete cube with the highest possible compressive strength. Among the competitors at this internationally diverse school was a team from the University of Tehran. Jay takes up the story.
"I designed a 2?x2? concrete cube with a compressive strength of 16,000 psi [pounds per square inch] at 28-days, a relatively high strength as standard concrete is on the order of 3,000 psi, typically. Now, The University of Tehran made several cubes between 50,000 to 60,000 psi, and possible stronger!
Superhard, penetrator, bunker-buster?
Doesn’t not compute - error - bad joke overload...
And if this report is true it just gives Israel another reason to attack...and to use her nukes.
This sounds like a professor at a university that won a contest with his students, it could well be employed in this manner, but it’s a far cry from being a standard material being used for bunker construction by a defense contractor.
BTW-Who does Iran use as a contractor for it’s bunkers or nuclear facilities? I’d bet it’s a Russian or German company.
I have met and worked with some very smart Iranians. I assume there are plenty more where they came from. Also, although Iran imports some refined petroleum products, they do have their own refineries.
Since Russia is building their reactor I would assume they are also pouring the concrete.
Or French....or Dutch.....or Belgian...or Italian....or Swedish....or Canadian....
Ahmadinejad hits his head against the concrete to test it.
well, thats it, best excuse to nuke there is
I seriously question how easy it is to produce large quantities of a 50,000psi concrete to protect something like an underground nucealr facility.
I call BS. I smell typical oriental hyperbole. Such claims of “Hyper-strong” concrete are a sign of desperation.
The Iranians are not stupid, but their “achievements” in science propagated lately are ridiculous.
Ahmadinejad claimed Iranian scientists can mass-clone sheep and have a cure for AIDS. Not to mention all the faux propaganda about Iranian developed “Super-Secret and Super-Sonic” Doomsday missiles, torpedoes and “flying boats”.
I wish I could make 50,000 psi concrete - steel is normally 30,000 psi.
Of course the trick with concrete is that it’s compressive strength is not the same as it’s strength in tension. Stuff must be quite brittle.
The same corner cutting Iranians that seem to crash a plane once every week or two from bad maintenance.
I wish them luck.
It was *stealth* boats, remember? lol
Best not to underestimate the enemy though. Between cruise missiles and stealth platforms we should be able to do quite a lot of damage without risking much.
Seems to me that making industrial quantities and pouring it is quite different from making a small lab quantity.
The Iranians have more than just one Refinery. The matter is their installations are dated and they lack the means to refine all their crude. Therefore they import the vast majority of refined stuff.
Last I heard, BB were dropped in pairs, one to follow the other down the ‘rabbit hole’....
Nukes OTOH - well, one is usually enough.
