The article goes on to say that the professor who sponsored the team works in Iran's nuclear industry, and goes on to point out how incredibly strong 60,000 psi really is. Our new Massive Ordinance Penetrator goes 60 meters through 5,000 psi concrete, but only 8 meters through 10,000 psi concrete.

Disturbing stuff.

......The University of Tehran made several cubes between 50,000 to 60,000 psi, and possible stronger!....

I Doubt it.

The compressive strength of granite is 1.300 kg/cm2 which works out to 18,490 psi

The compressive yield of Titanium is 65,300 psi

Its BS, I am in the concrete business and though I could tell the facts it may not be a good idea at the present time.

Time to outfit the MOAB for service.

A B-61-11 or a B-83 in lay down configuration will reduce such concrete to free floating dust particles.

[Steve Van Doorn]

Ultra-high-strength concrete is now manufactured with strengths in excess of 21,750 psi. There is no way Iran has anything better then that.

Okay. Ya’ll know about concrete. I have a question. Concrete floors just wear my feet and legs plumb out. If I walk in some stores for about an hour, it begins to feel like I have concrete blocks tied to my shoes. - Here’s the thing - some stores are worse than others. I have recently wondered whether some stores have denser concrete poured for their floors. I could not work on a concrete floor eight hours a day even if I was starving (I’m pretty sure of that, too.)
