Burn time? Coarse concrete, foundations for gate posts

[j-e.m]

Hi, I have cast a foundation for a gate post for a wooden gate (1.40 cm, not particularly heavy), with Finja grovbetong.
How long do the foundations need to cure/dry before I can continue working?

Thanks in advance

Normally, you have full strength after 28 days at 20*. But if you wait a few days up to a week, you'll be fine.
