I would not advise driving or parking on it for at least 7 days. While the surface may seem hard, the insides are not totally set and can be ruined. 6" thick will take longer than a 4" slab. 4", you could probably park on in 4 to 5 days. Got to think if you want to do it over for using before set properly.

You can not drive or park any heavy objects on fresh concrete for 28 days. the concrete is considered green and will not cure enough before this time.

concrete obtains its ultimate strength within 28 days. the concrete will still continue to hydrate, getting stronger but the ultimate strength is negligible by 28 days. you should be able to park / drive on it within 14 days. if you drive on it prior you stand an excellent chance of breaking or cracking the concrete.

i believe you have to wait somewhere around 48-72 hours for concrete to harden before you can do anything with it or to it.

If it is 3 -4 inches thick, I would wait at least 48 hours.

i tell everyone to wait 28 days to cover my butt...but realistically you should wait at least 2 weeks...most never do...
