/diy/ - Do It Yourself

preventing sag in a quarter pipe:

please explain to me why this is a bad idea for pouring a wall towards vertival, pic rel.
what if i poured one layer at a time... let it harden for an hour then poured the next layer, let it harden for an hour and then pour the next layer....
would each layer not bond well to the previous layer if there was a ~60minute break where it was allowed to harden?
what if i were to do thnner layers of concrete and give each layer 30 minutes to harden instead?
in a 6hour pour, i could have like 12 layers on a 6 foot quarter, the bottom layers being about a foot in elevation gain, middle layers around 6in in elevation gain, and final layers being only a few inches high each pour.

also why couldnt i do a pour in two days with a seam 2/3 up the ramp? surely a seam would be preferable to transition with an anti-pop lump in the center, aka sagging, ya?
