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.
What you describe as concrete is actually mortar. Sand and cement combine to mix mortar. (used ro setting bricks, for example) Sand and cement and an aggregate (small rocks) combine to make concrete. Any cementatious product reaches full cure in 29 days.Full cure being structurally safe, for example, that is when a tilt-up concrete wall can savely be lifted into place.oncrete cures essentially forever, although after 29 days, the rate of cure is dramatically reduced. For around home use, you are wondering how soon can you get onto the next phase of the project-whatever that project may be. It does depend on the project as to whether you will be safe or not.
