hi, you dont need to wait until concrete has finally set
which is at 28days, for grade 25 of concrete at 14 days it
will have obtained strength of 16.5N/mm2 when curing is done
well. still you dont need all that strength before removing
formworks, depending on the type of cement say for quick
hardening cement even 24 hours are enough, portland
pozzolana cement about 48-72 hours you can start removing
your formworks in case you need them for other purposes.
Note, the longer they stay the better, because when you
remove them early using rough methods you may slightly
destroy soft parts.
