Andy,
Since it was only a 14 ft long building, we used a 4x8 that was that length.
One could also opt for a glu-lam or another piece of engineered lumber.  As
for the connector, we used a substantial Simpson connector, I can't pull the
number of it down right now, but since there is a lot of stress at that
point, I think a few framing nails would simply pull it apart.  The trusses
were also attached with a standard Simpson connector, again I don't have the
number handy.  Like I said it worked well for that small building and with a
little luck it would work for something larger and not too complicated.  But
it would need some further experimentation and thought before unleashing
such an effort on a full size building.

As for the sodium silicate mix, to get it to work well, it really needs to
be integrated into the mix and it needs to be concentrated.  Typically it
takes a strength somewhere in the neighborhood of 1 part of it to 1 part of
water.  And at that concentration, to keep costs and material consumption
down, you are probably better off doing a very dry mix (damp) and tamping
it, dampening the surface and troweling it at the end.
