Your new concrete is designed to reach 90% of its full strength potential after 7 days, so feel free to drive your personal vehicle on it then. It will take additional time before you can drive or park heavy equipment or machinery on your newly poured concrete, so make sure to wait at least 30 days.
If you drive, walk, or park on your new concrete any sooner than the recommended time, here's what may happen: It may crack. You may leave tire tracks or footprints in the concrete, which could also ruin your shoes. You might weaken the future strength of the concrete.
Curing times for concrete After 7 days, the concrete will have gained around three quarters of its compressive strength, but you should refrain from driving vehicles or heavy machinery over the surface until after the 28 day mark.
Thus, it is clear that concrete gains its strength rapidly in the initial days after casting, i.e. 90% in only 14 days....Why do we test concrete compressive strength after 28 days?AgeStrength per cent1 day16%3 days40%7 days65%14 days90%•Aug 14, 2014
28 daysCONCRETE MIX STRENGTH: C35 C35 is 35 Newton's of strength per mm2 after 28 days of curing.
When waiting for concrete to dry, keep these timeframes in mind: 24 to 48 hours - after inital set, forms can be removed and people can walk on the surface. 7 days - after partial curing, traffic from vehicles and equipment is okay. 28 days - at this point, the concrete should be fully cured.

Although concrete will harden soon after pouring, it's still susceptible to damage from weight during the first four weeks. Wait at least 24 hours before allowing foot traffic, including pets, on a newly poured sidewalk or slab, and don't drive a vehicle on a new driveway for at least 10 days.
