Breaking Concrete with the MicroBlaster

[HerrCaZini]

what is the advantage of the oxy torch to for instance an angle grinder ? just wondering...

So we can see how much work was necessary to cut through just a 20 inch thick concrete wall.

Imagine if you had picked up a piece of concrete the same size as that door, and dropped it 3.7m onto the ground. Would it have turned into dust? Of course not.

But on 9/11, almost ALL of the concrete in WTC 1 and 2 was turned into dust, in MID AIR, while each floor hit the floor below it... Where did the energy come from? The floors were 3.7m apart.

how does those microblasters work? explosives?

Ive walked through that vault befor they put the hole in it.

How does this work when the concrete is reinforced? the reinforcement in this wall was almost non-existing...
