i blinked....

The load was most likely 190,000 lb....NOT 190,000psi.
on a 6x12 cylinder, that loading would translated approximately to 6,700psi, which is still pretty strong.
190,000lb = 845120N
You would get about 46,353,100 N/m² = 46MPa

@muchadoaboutnoting thanks! i saw that error too
-
That didn't quite sound correct so I confirmed: 190,000 psi is 1310 MPa, not about 100.

I see you've got a perfect cone left shaped by shear stresses :) The strongest concrete I tested was C55/60 and it behaved way differently - it just crumbled with no sound :)

repeatedly press 9 to see the explosion again and again
-
Thats the kind of explosion on a 100 MPa ... Im in civil ingeneer and we are doing test to get the highest MPa ... right now were at 45 MPa ... its splinting pretty hard ! that one is totally crazy !

that was a really nice cone

Two things may contribute to that in this video. The main reason is that the plastic molds used to make the cylinders leave a nice smooth surface on the concrete when the mold is removed. Also, you may be seeing a bit of glare from the protective goggles right in front of the camera. Most is from the mold though.
