Then maybe we should talk about how a granite mountain side is still probably harder than this super concrete! If only I could find more information on google rolleyes.gif.

23,000 to 33,000 PSI, tested to ~110,000PSI. This is Ductal though, the commercial equal to it.

I wouldnt be surprised if they needed the stuff. They got half the world who thinks they're up to something.

Don't count the Iranians out, they have some very clever engineers there; I am sitting next to one right now thumb.gif I just worry about the political side, as does he, as they don't seem to be all that stable.

This material and related reserach could be a huge benefit for lots of people. More earthquake resistant structures, better and cheaper(?) buildings that use less material, wider applications, what is there not to like?

Oh, and on the MOAB:

The MOAB is not a penetrator weapon and is primarily intended for soft to medium surface targets covering extended areas and targets in a contained environment such as a deep canyon or within a cave system.

Yeah, I had a good mate from University who was (and now lives again) in Tehran, Iran. It's a relatively well off country with some real smart people. It's certainly not so backwards as Iraq or Afghan.

Shame their Government and processes aren't more clear.

*snip*

have no idea, tbh biggrin.gif kinda skeptical myself (from some the issues i heard it had) of it being a functional hotel but just saying thats what i remember reading a few weeks ago, although i did run across some pics im guessing from October- February on a skyscrapers forum (didnt know that there are skyscraper forums tongue.gif), seems overall the project is at least to just to make it look better and less of an eyesore thumb.gif

on-topic...While I understand how this is great against things like bombs, what I don't understand is how they tie this stuff to earthquakes and compression. I thought the real problem with earthquakes was that the pressure exerted on structures wasn't uni-directional with a consistent force, but was instead varying pressures that could come from variety of directions. So how does a super hardened material able to better cope with earthquakes? Wouldn't its form make it even more fragile/brittle to an earthquake, or am I missing something?

Not a bunker buster, and wouldn't even be effective against even normal buried concrete fortifications. Same goes for any other thermobaric weapons.

Right now, the only ordinance the US has that is sure to be effective against deeply buried UHPC fortifications are small nuclear penetrators, and those come with all sorts of political baggage.

Anyway, an arms race is never a bad thing for one who owns stock in defense contractors.

If I was trying to protect a uranium enrichment facility I wouldn't bother with some new fancy concrete. I'd fill it full of babies and cute fluffy animals, nobody would dare attack it then. tongue.gif

On a serious note, can we all keep this thread on topic and avoid the WW2 willy waving. Discuss military history in another thread, cheers guys.
