Tom,
Base was poured in August 2012. I actually wrapped a blanket around the base
and kept that damp. This was recommended by the concrete vendor.
It has been in for over a year and already gone through one New Hampshire
winter with no issues.

One thing you might do is what I was told when I put in my base back in 1993.
Lightly water the concrete base daily. I mean lightly, no gushers, etc. Just
a sprinkle for a couple minutes. This helps take out the heat from the curing
concrete. I mnust have worked because my 4x4x6 ft base is still in fine shape
as when I put it in.

My US Tower first advised 90 days, but the eventually relented and told me
28. I think I waited six to eight weeks; don't remember now.
Remember, though, that none of us are structural engineers. You might want
to check around to be sure. But, I believe that's standard information and
you should be able to google something up from a reputable source.
