Only waiting 3 days for mine to cure. Have cinder blocks filled and a smooth exterior finish. wouldnt worry about it too much after 2 days.
It could, but it should not crack. Either the grade was not prepared properly, the concrete was used too soon, the concrete was not reinforced, it was allowed to cure too quickly, or some other problem existed.
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.
I't depends on many things temperature, humidity, and so on, but you should be fine after 7 days
what is the purpose of reinforcing bars in a spread footing
no, not normally. It will cure more slowly and how much slower depends on how much dirt is piled on it.

At least 3 days
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.

New concrete will need to cure for several days. Depending on how much weight it is going to hold, this should be postponed as many extra days as possible.

Yes and many so ask the supplier of your concrete.
Yes.
Generally 30 days brings concrete to to specified compression strength. Concrete may take 30 years to cure.AnswerConcrete will harden to about 80% strength in 2-3 days and close to 100% strength in 28 days. Concrete driveways should be towards the latter end prior to driving on them. AnswerAs a former concrete inspector, I would agree with the first answer. AnswerConcrete takes 50 years to completely cure and then takes 50 years to break down
no, not normally. It will cure more slowly and how much slower depends on how much dirt is piled on it.
all things that need to dry are based on 72 degrees concrete needs 30 days to fully cure.
