@freeupfarmDM I'd be curious knowing also. I think the size of the plastic particles would preferable be smaller than aggregate so as to not introduce microcracking over time. In the Dominican Republic styrofoam is a significant problem, there is some repurposing: http://www.appropedia.org/Practivistas_Dominicana_Program_invitation#Application
I am also interested in what other potential or ongoing challenges Domes will have with climate change and our current materials utilization i.e concrete vs. earthen/clay, plastic/polymer blends etc.
This is the best air compressor company to buy one from.
You have a lot of different size air compressor to pick from.
Make sure you can get free shipping from where ever you order from.
This is a short video I did on my air compressor setup.
@fire Earthbag construction is so labor intensive but not as labor intensive as packing tires. I personally am going with the Monolithic Dome airforms. You could make your own airforms I have not done so myself, but i visited a home in CO where the home owners made the airforms. On there website they sell a book on how to make airforms.
Here is a video I made of the home i visited and I have a link in the description to the website with the book.
