Hi,
I have had a lot of luck with fiberglass reinforced concrete; in the sense that it does not crack a lot. I also use mesh. But, you need to make isolation at around 25-30'. It will shrink and you need to isolate to keep it discreet. Use a relatively weak mix, say 2500 psi, with as low a water content as your contractor will allow. Make sure you have at least 4" of gravel underneath to evacuate water.

Check with Graphic Standards, your favorite Civil or Structural Engineer, the best small concrete Contractor in your area, or the best pool Contractor with the best reputation.  Last would be the best home builder or one of their superintendents.

​Fiberglass fiber or wire mesh (grounded) is fine. Concrete should be 4000 psi with low water content. Joints at 20' max.

Refer to IRC Section E4204 Bonding (E4204.1.2 Perimeter Surfaces) under Chapter 42 Swimming Pools.

Your pool contractor should be knowledgeable about the code requirements for grounding and bonding, which should be inspected before pouring. Do yourself a favor and put in a handrail; if it's stainless steel, it needs bonding; if it's PVC or FRP, it doesn't.

That said, pay heed to the concrete mix and reinforcing suggestions already offered. There may not be enough cement in a 2500# mix to allow for workability, but the commenter is correct in that the more cement, the more water, and the more shrinkage. Residential level concrete contractors don't like to use water reducing admixture due to cost and unfamiliarity, but it is a good idea ifor a pool deck. Also, limit the distance between shrinkage crack control joints to short distances (12 feet maybe?) and remember that concrete wants to be square, not rectangular. Narrow rectangular portions will crack. Pool contractors use several kinds of PVC inserts at crack control joints that might be worth considering.

Go and look at the workmanship in a few 5 year old installations before you sign on with a pool contractor. Also - remember you have to walk on whatever surface you choose, both when it is wet and when it is hot. The most practical and least sexy pool deck finish is something like H&C's AcrylaDeck CoolFeel applied with a knockdown finish.

The Trouble Free Pool online forum is a marvelous source for more pool knowledge than you can ever absorb. Best of success with your project!
