Only waiting 3 days for mine to cure. Have cinder blocks filled and a smooth exterior finish. wouldnt worry about it too much after 2 days.
It could, but it should not crack. Either the grade was not prepared properly, the concrete was used too soon, the concrete was not reinforced, it was allowed to cure too quickly, or some other problem existed.
Concrete never fully cures, but a non-quicksetting concrete should be firm on the surface in about 4-8 hours, and usable for foot traffic or post setting in 36 hours.
I't depends on many things temperature, humidity, and so on, but you should be fine after 7 days

no, not normally. It will cure more slowly and how much slower depends on how much dirt is piled on it.
Concrete should cure for at least 28 days before it can be used for construction purposes.

At least 3 days
A concrete driveway typically takes about 28 days to cure completely.
It is generally safe to drive on concrete after 5 days of it being poured, but it is recommended to wait at least 7 days to allow it to fully cure and strengthen.
28 days is the usual cure time for structural concrete. For street pavements and driveways made with 6-Sack concrete, 3 days of cure will support a car, but 7 to 10 days is required for it to support trucks. All concrete continues to cure forever, as long as moisture is present.
It typically takes about 24 to 48 hours for 6 inches of concrete to cure completely.
Concrete never fully cures, but a non-quicksetting concrete should be firm on the surface in about 4-8 hours, and usable for foot traffic or post setting in 36 hours.
New concrete will need to cure for several days. Depending on how much weight it is going to hold, this should be postponed as many extra days as possible.
It typically takes about 28 days for 4 inches of concrete to fully cure and reach its maximum strength.
