[TowerTalk] Concrete Base?

[Kelly Taylor]

Isn't it one of LXC's tips to order 4,000 psi, which cures to 3,000 psi
rather quickly? I forget the exact times, but it seemed that ordering
stronger concrete than you need shaved considerably the wait for the design
specification strength. Then the extra curing was gravy.
