Why would anyone want to "ground" a tower thru cement?
If the cement is "wet", lightning will conduct thru it, blow it to bits if it's
a large strike, and your tower will float away to Jupiter.
If the cement is "dry", lightning will see it as just a little lossy insulator,
blow it to bits if it's a large strike, and your tower will float away to Mars.
Your only hope is not to use cement..., and hope it stays in Earth.
