Does anyone know where I can get Ciment Fondu (calcium aluminate)?

So I got an amazing book by Su Chin Ee called Creating Bonsai Landscapes (great book, highly recommend) and she talks a lot about a product she uses to make rocks called Ciment Fondu (kinda like Kleenex as far as I can tell, the "facial tissue" version is called calcium aluminate cement). I have looked at hardware/construction stores as well as craft stores and even reached out to a professor who teaches sculpting trying to locate a place to purchase this material but I am having an extremely difficult time. I have a lead through a place called Kerneos but they are like large-scale and haven't been responsive so I am not sure if they would even sell me any. Does anyone know where I can get it? Or do you have a good substitute that is safe for trees and fish? I'm putting it in a bonsai/fish tank so it cannot be a harmful material for either and it will also have a fountain inside the finished rock so it needs to be able to withstand the water as well. Thanks in advance!

How to remove serious calcium/mineral deposit from cement wall?

https://imgur.com/a/37aFmsx

I want to paint this area but first tend to the bumps of calcium or other minerals that have accumulated over the years on this spot. What's the best way to get rid of it?

How to finish this wall without lime? Lime has been outlawed in Indonesia (locals were blowing up reefs). Locals now render walls using only cement and sand, which I have been hesitant to do because of the low permeability issue. We have calcium carbonate and some instant plaster available. Advice?
