Today, Brent conducted the drop test of his experimental "bricks". Now, as we aren't building walls with them, the test isn't quite so critical. Brent held each brick at chest height and dropped them onto a corner on the dirt in the yard. All of his bricks passed this drop test - no breaking or crumbling of the corners that hit the ground. This is great news!
We'll be constructing what will essentially be a bond beam out of soil cement. The outer edge of this beam will be the circumference of the yurt. The beam will be between 3-4" in width. A bender board will be used as the outer form for the bond beam. The bender board will be a little taller than the bond beam. The lattice of the yurt will rest on the bond beam, pressed out against the bender board (that is what will keep it from being of greater circumference than we need). The lattice will be attached to the bond beam with "L" shaped metal brackets. The interior floor of the yurt will be straight adobe.
This is 90% soil, 5% portland cement and 5% hydrated lime.
This is 95% soil, 2.5% portland cement and 2.5% hydrated lime.
This is straight adobe and will be our yurt floor.
We will be using linseed oil (boiled most likely) to seal the floor and bond beam. We may use some melted beeswax in the last coat to create a harder wearing surface.
