I would like to know if aircrete will bond to my refractory if air create is cast over it. Maybe try at 24, 48, and 72 hours. I expect the refractory to be too weak to demold at 24 hours but if the other two fail it may be the best option.
Plan
Cast 6 refractory slabs in the new slab mold.
Let the refractory set wet for 1 day.
Starting then coat two of the slabs with aircrete every 24 hours.
I could do 1 every 12 hours but don't want to double the aircrete mess.
The aircrete foam will be made with an electric hand mixer. Need to come up with a foam generator.
UPDATE
Shortly after writing this I was thinking it was a waste of time. As long as I make a refractory shell that can support itself it will work. But what I can do with this is try different thicknesses of aircrete to see how much is really needed. But I am still unsure if this is worth my time. Need to think about it.
