According toUniversityof California, Lawrence Livermore National LaboratorytheCompressive strength of typical construction concrete is 5000 lb/in2I have read that specialty blends can exceed this by more than a factor of 6.
On what?
800 C feet
Jackhammers are commonly used to break through hard material. When I did demolition we used a full sized sledge to take down pretty much everything including cement and bulletproof glass. If you have access to them, than explosives would work well. Don't use the latter option if you do not have an extensive knowledge of them, serious injury or death could occur.
The top of a CO2 canister isn't very thick. It will take about a half a pound of pressure to break through the top.

50 psi
550 lbs. of pressure
75 pounds of succinct concentrated opposing downward pressure will break almost any human bone
It takes about 7 pounds of pressure to break an elbow according to the UFC

Look on Mythbusters. They have a whole episode about duct tape.

It is not so much as how much pressure as where the pressure is applied. If you keep the egg upright and try to apply pressure at the top and bottom, the egg won't break as easily as much as when you apply it in the middle. The shape of the egg gives greater tensile strength to the ends but the middle is comparitively fragile.
"depends on thee bone. Copperhead_51 " That's wrong. As long as there would be no gas in something, the thing cannot break under any kind of pressure (unless you have pressure equivalent to a sun or blackhole). At some pressure, chemicals can start to break down, but your bones would still not break.
It would only take about 30 pounds of pressure per square inch to break a human neck. At 25 pounds of pressure, it causes instant unconsciousness.
