What is a recipe for refractory cement in small amounts?

This has me wanting to make my own foundry, however i can't find how to make refractory cement, and nutandbolt doesn't list his own recipe.

Alternatively, Where can I buy refractory cement in Australia?

It should be available at professional builders supply stores, and in small quantities at DIY big box stores. (I purchased a ~1 gallon container a couple of years ago to do tuck pointing on my fireplace's firebox (although I still haven't gotten to the job yet...grrrr)
You need to look for sources of "calcium aluminate" -find a good traditional "builders merchant"
