Curing time for fine concrete?

[snowjim]

Hello,

We set up a mailbox (post) yesterday, and for stability, we poured down fine concrete (Bygg Max) instead of earth. The question now is whether I can install the mailbox today so that mail can be delivered, or should I wait a few more days?

The block we put down is maybe 20x20 and 20-30 deep.

Answer: Yes.

Yes on whether we should wait a few more days?

A day should be enough.
Sorry for being unclear.
