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

[Bill Kendall <KENDALL@nucusa.com>]

I haven't kept up with recent developments but a cement contractor told me
once that accelerants should not be used on thick walls because the center
would not set up correctly.  I would want a Civil or Structural Engineering
opinion.

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.
