Hello fellow oven builders,
In another post, David S mentions using carbon nanotubes as an admixture for the castable dome concrete mix. The product he uses is called Edencrete, however, after researching the tech, it appears there are many suppliers, I was able to find some on Alibaba in both liquid/paste and powder form. I wonder if anyone can contribute some tribal knowledge on actually using the stuff, finding dosage info in layman terms is proving to be difficult.
Anyone planning to cast a dome should definitely look into it. For my first/only oven, I used 3:1:1:1 homebrew with polypro burnout fibers, and though the oven works great, I was not satisfied with the perceived hardness of the final product and ease of dinging the wall. My current project will be a bit bigger and I don't want to worry about eventual collapse, I think graphene aka carbon nanotubes will address the issue.
Looking forward to your thoughts.
