4.How long does it take for concrete to dry enough to walk on? Wind, humidity, and sunlight are all factors in how long it takes for concrete to cure, walking, normally about 1 to 2 days. 5. How long does it take for concrete to cure enough to drive on? Again, wind, humidity, and sunlight are all factors but the standard is about 5 to 7 days. 6. Should I put cure or water on the concrete? Yes, after the initial 12 hours applying cure of water for 5 days every morning and night is recommended. 7. Do I need to use base rock for my subgrade?
I agree with Jason S. It gets about two thirds of its strength in 7 days Concrete is considered cured from a technical standpoint at 28 days.Most designs are based on the 28 days strength of the concrete mix.Most design mixes exceed the 28 day design stress before 28 days but that can vary depending on many variables.est Answer: It really depends on how wet the ground is and the ground temperature. As a rule you should wait at least a week before starting a construction project on new concrete, 30 days is even better.
