Their instructions for pouring the base should specify the strength!
It will probably be something like 3000 PSI. I had concrete pumped
in for my tower (Tri-Ex) a year ago, and ordered 3000 PSI minimum.
The concrete supplier said that the mix for pumping runs well over
that... about 4000-4500 PSI.
A good concrete supplier will test the "slump" and adjust it for you
when they pour.
Read the instructions that came with the tower/base! Go with what
the tower mfr. says. You don't want to get this wrong, and have to
redo it.
