My understanding is that -- in the US, at least -- the specified
strength of concrete is achieved only after 28 days. What percentage it
would have achieved after two days, a week, two weeks, etc., I don't know.
I have been quoted an 8-week delivery delay for the tower I have in
mind, but I can get the base plate and bolts delivered ahead of time so
that the concrete will have had at least the full four weeks to harden
before I put any load on it.
