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.
The advantage to sealing new concrete with a cure and seal is that the concrete does not have time to get dirty or stained. If a cure and seal is not being used, then you should allow the concrete to cure for 2-4 weeks. The industry standard is 28 days but that depends on the climate and mix of concrete. It is important to wait and not to seal new concrete too soon. Trapping moisture in the surface will likely lead to a premature failure of the sealer.
