[TowerTalk] CONCRETE CURING

[Mike, K6BR]

Well, it is all relative is it not; I would not think you would put 750 foot
stack on a 5x5 base.  The principle for curing time holds true I am sure
even when you scale it down, I am glad I said 4 weeks; my XYL always says I
know everything and that I am always right, so you guys have confirmed that.

As Larry say's that is what US tower recommend, and we all know we should
follow the manufactures recommendations.

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

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.
