What is the recomended minimum psi concrete for a parking pad 8 ft. wide by 22 ft. long by 6 inch thick? on a reinforced tamped gravel bed. And or what would the optimum or recomended psi be? How long to mist and no load cure time?

Any info is appreciated.

4,000 psi. Air entrained. Full strength will be acquired in roughly 28 days, but will withstand light traffic in 72 hours or so. Broom finish for a little bit of traction if desired. Be sure to cut expansion joints at initial set, or set the fiber board joints before you pour at approximately 1/4" below the desired concrete surface.. Caulk the joints after concrete cure.
