Drying time of concrete.

[Corsair]

Hello, I have cast a post for the fence. The dimensions are 120x20x20cm. What could the drying time be?

Maybe good tomorrow?

Hi
It depends on the mix and temperature.
Wrap everything in plastic so it doesn't dry too quickly, and preferably wrap it in something if it gets below freezing.

If you mean before you can release the mold, wait at least 2 days, preferably 3. I assume you are planning some form of attachment to the fence? Wait at least a couple of weeks before doing that to avoid any damage.

It depends on the temperature. Then it should not dry but harden by the water chemically reacting with the lime. Therefore, the concrete should be kept moist during the initial period after casting.
