Generally 30 days brings concrete to to specified compression strength. Concrete may take 30 years to cure.


Concrete 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.


As a former concrete inspector, I would agree with the first answer.


Concrete takes 50 years to completely cure and then takes 50 years to break down
