Thanks for the ideas. What is the source and is there a movement to facilitate these building concepts?
Even adobe walls that have fiber reinforcement are prone to breaking apart at the joints. Ladder joint or othe steel reinforcement is prefereable, but the problem reverts to costs. (Bamboo, though an organic material, has been investigated as a concrete reinforcement. Possibly better than nothing). The weight versus the tensile strength is still going to be a problem. And rich countries that still have trees have the greatest advantage of using frame structures.
Addition of bond beams in masonry structures is also helpful and may be cost effective in some areas.
Another line of study has involved "firing" adobe structures to glaze and bond the material together. This was done by a middle easterner who lived in the US years ago. So long ago, I forget his name and have not heard of it recently.
