Catherine:
I like portland cement (available almost everywhere) with a bunch of extra sand for more moisture retention, but really depends on what you’re ramming the bottles with and how rigid they are going to be. What’s the mud like where you’re working? Obviously you don’t want the mortar more rigid than the walls themselves.
I think it always comes down to tests (realizing you probably don’t have much time) of a range of materials.
We just mounted this exhibit in Denver... http://artofdirt.org
Just yesterday I added a prototype of a solar steam pump we’re designing for Africa. Pumps 12000 liters per day on a little water and sun. I’ll be adding a virtual tour to that site above. You can keep up there.
By the way, are you looking for roof construction? I’m involved with a group here in Denver that uses thin shell composite hypar. Very light, strong using locally sourced materials, and easy to learn...
