1 million lbs of pressure! wow, never realised a concrete column could take so much.
Thanks Gman..

While that is a lot of pressure, the actual strength of the concrete is not as great as you might think. It is hard to tell in the video, but if that column was say 18 inches in diameter that would equate to around 3937 psi (pounds per sq. in). Normal highway concrete will reach that after 7 to 14 days of curing, whereas bridge concrete will exceed that and be upwards of 6000 psi in 7 to 14 days.

Endo most impressed with Ferg's knowledge of material science and compressive strength of (different grades of) concrete.
