RE: Use of accelerant in cement - re: accelerator shield wall

["Lavera, Ron" <Ron.Lavera@nypa.gov>]

I'm not a accelerator or structural design type, but I am aware that some
hardening agents may have a polymer base material that may not maintain
structural integrity under conditions of long term or high level exposure to
radiation.

		Comments requested: Any experience re: the  use of
accelerants in cement for
		quicker set-up time.  We are running into some weather and
contract
		schedule
		problems on our new U. Hospital medical accelerator project.
So the use of
		an
		accelerant is being floated.  I would prefer --" plastic
tents with portable
		heaters at this point."  I think accelerants have only been
used for about 8
		years ...  not much of a performance history there. If you
have dealt with
		this
		issue I would appreciate your input.
