  I am not real knowledgeable in this area, but I would assume that
  you
  would have to set up an array of electrodes thoughout the concrete
  system.  I also read that there are some studies being done to find
  out
  if cathodic protection has a long term effect on the bond between
  the
  steel and concrete.

  Do you just put a bunch of electrodes on the surface of the conrete
  and
  run a low voltage current through them?

  Sorry if these are stupid questions, but I really am in the dark
  when it
  come to cathodic protection.

Lynn,

For a quickie read-up on CP, try the Oct/Nov issue of
CONCRETE REPAIR DIGEST 1993, pp 256-262.  If it's not available at your
local library, try any of your local concrete suppliers.
