Concrete Pads for A/C Condensers. Cure Time?

Poured a couple of pads this weekend for condensers. The pads are +/` 3 1/2" Thick. Humidity was probably around 60% or better on the day of the pour (Sat), Sunday it was decent until evening, then it rained. Relative humidity today is 85% with possible rain today Wed. The condenses weigh about 140lbs each. I doubt we will get anywhere with this till next week at the earliest. So that would be set for over a week. I don't need to wait the full 28 days do I?

No it will be fine.
I almost never pore pads anymore, I buy the premade fiberglass over foam one's.
Cheaper, lighter, look just like concrete, and far less work just set them in place.
