Flagpole when to note after burning

[berne88]

Just poured a footing for a flagpole. A 12m one, how long does it need to cure before the flagpole can be mounted?

2-3 days, 1 week if it storms

It has burned enough that you can walk on it after a couple of hours. So a few days work without any issues. But I would have probably waited a week anyway. Just make sure the ground is well packed so the foundation doesn't shift.

Real concrete. One day.

At least 3 days, water thoroughly every day if it hasn't rained for a long time or the ground is dry. It's best to lay plastic in the hole before casting.
