[TheForge] High temperature cement?

[Jeff]

I haven't done it yet to many other projects, but to line my 
coal/charcoal burner I have 1 part portland cement, 2 parts fire clay 
and 2 parts vermiculite.  I was told to mix as dry as possible and pack 
it in place and let it dry slowly a week or two before the first fire to 
avoid cracks.  I was told this would last even considering in my case 
the fire pot will be constructed out of the cement/forge liner.  I think 
there is a similar recipe on Anvil Fire.
