This photo shows the near impossible to make perfect fit between stones that indicates they may have been cast in place with geopolymer. One source said iron tools were not available at that time, only copper. Ever tried chiseling and cutting hard stone? I have and I can tell you it’s ridiculously slow even with modern diamond embedded power tools.
Geopolymer is the latest hot topic here at our Earthbag Building blog. There’s a groundswell of interest already building as you can see in the Comments section of the previous blog posts listed below. Obviously people want to learn more about how to build a cast stone house with earthbags that has all the advantages of stone houses without the expense. Bit by bit the pieces are coming together, but unfortunately there is no book available on geopolymer house construction and so it’s going to take a while to do experiments and build a prototype.
