Concrete floor in a Pole Barn
Hope there are no livestock in the barn's future. Concrete floor is a no-no as far as livestock are concerned.

I wonder what all these poor dumb farmers have used for floors for all these years, and continue to use?

Harvey, I see you have r 4's with chains front and rear, how do they work in the winter as far as ice or snow and on steep grades, looks like you have some grades there? Nice place.

If you are not going to heat it,I would put an inch of styrofoam down to keep the frost from heaving it and breaking it. The posts are an unknown as far as any movement
unless you dig one and see what you have.Previous owner available?
The poly serves two purposes, a vapor barrier, which you don't need (unheated) but also gives you a harder concrete
by allowing it to stay wet longer in the cure process.
The longer the better. The floor finishers don't like it because they take for ever to set up. But will give you a much harder surface. Tire chains, changing implements etc.
If you pour it around those posts and they move?it will bust the floor. You can add fiber and go to a 4500 lb mix
for short money. I also take a piece of 2"x2" angle weld
a few 6" bolts to the inside and press it into the leading edge of the concrete(right after pouring)at your door entrance. It really saves that edge.
Good luck!

One other thing to add to your specs. Don't let them place the concrete with more than 4" of slump, and make sure the grade has been done properly to drain to a door or a floor drain, but still have consistancy in the thickness of the slab. If you don't keep the mix stiff ( less than 4" slump), you can expect cracks even if it is sawcut. Too much water in the mix increases curing shrinkage and will crack the slab. Inconsistancy in the thickness of the slab will also lead to cracks. Keep the mix stiff and consistant thickness for a good slab.
You can judge the slump by dropping a little concrete out of the chute onto the ground. If it stays mounded, with no run off, it is probably dry enough. A real slump test requires some equipment and procedures that probably aren't available to you. Good judgement is all that you will need. A lot of contractors like to add water to the mix to make it easier to place. Try to avoid this. Good luck.

Good advice, those guy's love to add the water don't they?
Make's it easier for them and the customer pays later with
a crappy result.
Put it in dry and keep it wet!

Stonegate,
If you plan to have any livestock of the four footed variety the National Electrical Code now requires that the entire slab be electrically grounded. Around here not all inspectors care, but some do and I know of one 24 stall barn floor that had to be ripped up and retrofitted.
You can just join all the rebar or wire mesh together and tie it into a grounding rod. Note that two footed critters (fowl) are exempt, but horses, cows, pigs and llamas etc. require it.
