NE ND | My screw ups in concrete are as follows:
If you think you need three people for the pour, get six.
Start at 6 am versus 1 pm with 80 degrees, I'd wait for an opening versus the hell in the heat. BTDT, maybe OK for guys with experience, but not green horns like I was.
If your friend knows stuff about concrete, get advice on slump. I did a little garage and it was too dry, set really fast, not fun.
Soak your gravel down really good so it isn't pulling moisture out of the concrete.
Yeah, lots of rebar. Father built three 27' bins in 83, no rebar, huge cracks now, size mice and rats can crawl through. Bin next to it he did two years earlier with rebar has nearly perfect floor.
Rent a power screed. Pulling a board back and forth can be a man killer.
Rent a bull float and maybe power trowel?
If it is 80 out have a couple of water jugs, pretty hard to stop for 90 minutes.
Take hammer and tap sides of bin forms, wish I'd have known that trick.
If early in spring, have 4wd tractor available so when cement truck driver backs into wrong area and gets stuck you can pull him out
What else?
Oh yeah, rent a plate compactor and get the fill packed down very well. Shouldn't be able to push standard screwdriver in if done well.

Concrete for grain bin?
