Let's say you were going to pour a 56' x 75' x 8" pad inside a shed on a gravel floor using rebar reinforcement. How long would you let it "set" before driving any 20-40K # farm equipment OVER it?

How long would you let it cure before PARKING any 20-30K # farm equipment over it?

How long would you let it cure before PARKING any 80K loaded trucks on it?

Again, this is inside a shed...no sunlight drying.     

Thanks
