Im curious everyones opinion on cold joints in the walls.
For example, if one wanted 14' walls, with another 18" or so needed below grade, thats a tall wall for a DIY to pour. Add a vaulted ceiling with ICF gables and it grows taller yet. And I dont think it could be vibrated that deep either.
So, could you pour that wall in 2, or 3, separate pours? I heard a rumor once that green concrete, if less than a week old, would meld together with another pour on top. I don't think that's true however. But with sufficient variations in height and a rough edge, you could get enough of a mechanical bond between the layers I believe.
Could you pour roughly 6 feet at a time and do this in 3 stages? Using a conveyer truck would save pump costs. |
