[TowerTalk] on guying towers

[bob finger]

I do not disagree with the rebar fully imbedded in concrete approach.  I 
do have a question about it tho.....for bridges, overpasses, buildings 
etc it makes good sense.  But for a tower job that likely has a life 
expectancy of less than say 25 years (hams move, lose interest, become 
sk's etc) before the tower comes down can anyone postulate or provide 
evidence of concrete block degredation during that time frame because 
the re-bar rusted, or water infiltrated due to exposed rebar.  My common 
sense tells me we are really doing things with a belt and suspenders 
approach.  What contradicts my common sense thinking?  This is only to 
be considered an educational exercise, not a license to violate building 
codes or common concrete practices.  73 bob de w9ge
