, no stress on the concrete for 6 weeks after the pour.
Even lowering the tower straight down, that is still a fair
load/stress for concrete not fully cured, or at least almost cured.
The last few % takes a long time.
They stressed that with concrete, let it cure properly and don't rush!

The % of cure asymptotically approaches its final value (gets closer and
closer at a slowing rate of approach) so that theoretically it never
quite finishes curing but gets close enough for most practical purposes
(90% of the final strength) in 28 days if the temps aren't extreme (hot
or cold.) Keeping the pour wet, especially the first several days is a
good tactic.
