Windage,
You've got me doing it now.
"The lime also acts as an accelerant with calcium silicate cement." In my previous post.
Of course I meant Calcium Aluminate.

Windage,
You are quite correct. The FB recipe does include lime and CA cement. This is wrong and should be changed. Obviously the recipe had not been tried, or the author had no knowledge of the incompatibility of the materials. I only found out through discovery when I tried adjusting my recipe and adding lime. On researching the product info it also says the two should be avoided. James can you amend the recipe?

I invented that group of chemical-sounding-words to make myself seem important and mysterious. The fact that others too, such as yourself, are using this catchy term, indicates that there may be a market for yet another, even more difficult to use mortar.
I will begin work on developing "aluminum-silicate" cement immediately!

Staying up into the wee hours reading data sheets and techinical specs about CA cement and the bonding/melting of silica sand is probably how I came up with that..and now I've polluted your mind with yet another useless piece of garbage...apologies.

AHA ! I re-discovered the place I had read about alumina-silicate, (just one of the many ways I have corrupted the name Calcium Aluminate cement);
