[TowerTalk] CONCRETE CURING

[NØATH]

At the KCPL power plant where the concrete stacks are 750 feet tall - they 
said
the magic number for max strength was 28 days.  A lot of difference between 
a
750 stack and a short foundation though. Not trying to add fuel - just 
commenting

I would say one week is not enough, remember the compression/tension from a
tower in wind is a lot more stressful than foundations.  I think you are
guessing, the people who poured my concrete said they always recommend 3 to
4 weeks for towers or longer for complete curing.

Most builders will cap a foundation within a week of a pour.

Lots of them  will start framing at the same time. My sense is a week
is good enough.
