There is also failure in creep.

I think it can work if the failures are simply some cracking. But Tim is right. I’ve seen overhangs. We usually post tension in the transverse direction. Plus we have lots of rebar. Lots. Lots.

I’d love to see a pic of what Fred’s got cooking over there.

I always joke with my concrete venders. If I do a pour at my house, I’m pulling a mix design from my files. I’m pouring a high strength mix. Driveway cracks? Sure. My tree roots are gonna struggle.
