Disturbing stuff.
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.
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.
Can we get some input from any engineers out there? This stuff must have drawbacks or we would be using it ourselves.
“Iran makes superhard concrete”
In other news:
“US finalizes work on superhard concrete penetrator”
I get a knife, you get a gun, etc, etc, etc.
Yeah, well we were just testing some super bunker buster, so we’re all back to zero even if this is true.

I’ve been running through this scenario in my mind. Instead of B-2 bombers, we airdrop Bechtel technicians along with the 82nd into one of their remote nuke sites, wipe out the Republican security guards above ground with some A-10’s looking for something to plink, while providing air cover with all our assortment of infinitely superior fighters, and then settle in with an infrastructure of PX’s, bowling alleys and dental clinics to handle the medium-term project of blasting the little rats out of their super-duper concrete rathole.
What could they do? Protest that we were squatting in their remote desert? We could just tell’em to evict us whenever they can must muster up a Marshal.
Come on folks, no need to get your panties in a wad.
Compressive strength tests are conducted with a static fixture and usually a hydraulic setup to generate steadily increasing forces while measuring displacement.
Tensile testing is conducted by pulling samples apart. Flexural strength evaluates how the stuff bends under lateral load...
This is a far cry from impact testing at Mach speeds. Hard materials are generally very brittle, which means they don’t stand up well to impact. Consider a diamond for example, it’s referenced as extremely hard (w/o going into the numbers), yet you can smash one into smitherings with a hammer.
I thought a Canuck university holds the record for the strongest concrete mix. I could be wrong however. It was then used in a concrete toboggan competition.
Remember the "Mother of all Battles?". That is typical bluster and hyperbole.
The strength of the concrete just guarantees a stronger, more permanent tomb. The achiles heels of any facility is the access, the entrances. destroy those and everything else is irrelevant.
If the facility itself can't be penetrated by large bombs, the interface with the original terrain is not. Ever try to open a door with 100 tons of dirt stacked up against it?
There is no protection that the mind of sandmaggots can devise that the minds of normal free people can't circumvent.
