[TowerTalk] Fiber reinforcement instead of rebar?

[kr7x1 at verizon.net]

Dan:

"For engineering reasons that don't bear explanation" this is the worst 
type of foundation to try and use fiber reinforcing to eliminate rod 
reinforcing in a foundation. I have posted to the reflector several 
times where fiber reinforcing is applicable and it is not in structural 
foundations. A good source of information can be found if you google " 
concrete- fiber reinforcement uses.
