Re: [WISPA] concrete cure period
Concrete cures fast. Manufacturer and engineers will tell you 30 days. We have done towers in less than 10. Concrete cures to like 90% of its rated strength in 5 days under normal conditions.

Re: [WISPA] concrete cure period
We waited 3 days for one yard. Put in a 60 ft tv tower (used brackets at the first second floors) on a cold day.

Re: [WISPA] concrete cure period
I think it should be 28 days, regardless of the size.

Re: [WISPA] concrete cure period
My girlfriend does concrete for a living. If you are in freezing temps, 28 days. If you are above freezing, 14 days. For a standard 4000psi mix. chris cooper wrote: Does anybody know how long I should plan for concrete cure prior to tower construction?

Re: [WISPA] concrete cure period
Under normal conditions is a key phrase. Colder takes longer. Drier takes longer, if it ever sets up. Also depends on the mix. I would suggest asking the concrete company what the cure time is. I have done a 100' and a 140' freestanding. I waited the full 30 days because multiple contractors reminded me that it is hard in 5 days when it is 8 thick like a basement wall. At 3'x3'x8', I doubt the middle will be hard in 10 days, let alone cured. I go for safety first, I would let it sit for 30 days. lakel...@gbcx.net wrote: Concrete cures fast.
