Sub grade is the issue, frost in Buff would be approx 36", if you are in granulars the soil is not frost susceptible . If you are in silts and clays you need to remove 30" of material and replace with Gran B or A and make sure you add sub drainage so the grans do not get saturated. Alternately you could provide 12" of gran along with 2" of Sm rigid insulation under the slab, plus drainage. Insulation and granulars must project 36" beyond the 20' x20' perimeter of the slab.
After that if you want to use a simple flat plate that will work without saw cuts as long as you provide reinforcement, use 4x4x6 ga welded wire mesh in FLAT SHEETS, and a 5" slab, 4 percent air, 3" slump, 4000 psi ( salt protection ), do not, do not, under any circumstances add water to the mix on site!
If workability is an issue use a water reducer in the mix or super P.
Ensure your steel is pulled up in to the centre of the slab, I would also use 2 slip sheets of 6 mil plastic under the slab and make sure the sub grad is very flat. This will prevent shrinkage cracks. If you go with thickened perimeter as suggested in other posts you will need to saw cut the slab into 10x10s as the slab will crack. The thickened edges trap the slab from expanding and contracting symmetrically.
You also need to provide proper curing, use a curing compound, avoid pouring on hot dry days with wind. Cool, cloudy days at 50 degrees are the best for amateurs.
