Concrete never fully cures, but a non-quicksetting concrete should be firm on the surface in about 4-8 hours, and usable for foot traffic or post setting in 36 hours.
Pre-mixed concrete is beter as it made to BSI standards and hand mixed (dry bagged) can be weakend by an inexperianced person mixing it. But it depends on what you are using the concret for; if its just a slab for a garden shed to go on it dose not realy make much differance, but if its structural you best get it pre-mixed.

It Has Been Said Over 100 Years, Most Times In 24 Hours. If In Doubt Give It Another 12 Good Luck
no, not normally. It will cure more slowly and how much slower depends on how much dirt is piled on it.
A concrete driveway typically takes about 28 days to cure completely.
It typically takes about 24 to 48 hours for 6 inches of concrete to cure completely.
clinker is the type of concrete after it has been bagged.
It typically takes about 28 days for 4 inches of concrete to fully cure and reach its maximum strength.
Concrete should cure for at least 28 days before it can be used for construction purposes.
28 days is the usual cure time for structural concrete. For street pavements and driveways made with 6-Sack concrete, 3 days of cure will support a car, but 7 to 10 days is required for it to support trucks. All concrete continues to cure forever, as long as moisture is present.
Bagged Premixed Concrete will achieve an mpa strength of around 20 mpa and is usually expected to reach this at 28 days. The "Rapid Set" Premix Bagged products are only good for about for about 5 mpa. .
At least 3 days
Concrete typically needs to cure for at least 28 days to achieve maximum strength and durability. During this time, the concrete undergoes a chemical process called hydration, which strengthens the material and improves its durability.

But it depends on what you are using the concret for; if its just a slab for a garden shed to go on it dose not realy make much differance, but if its structural you best get it pre-mixed.

Concrete forms should generally be left in place for at least 24 to 48 hours to allow the concrete to properly set and cure. Leaving the forms on for too long can make it difficult to remove them and may result in damage to the concrete.
