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?
That depends on the concrete, as well as weather conditions, and the load the concrete would be subjected to. Concrete gains strength over time and the usual benchmarks are 7 â¦ days, and 28 days. At 28 days concrete has usually cured to nearly its maximum strength.ypical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete.
