The technique was (as far as I can recall) introduced in 1980 and labeled as "Dry Block Building" construction. It was featured in architectural books at that time (I was hoping to be an architect and actively studied things on my own before college). And yes, this is a very strong building technique. But there is concrete and rebar in them also at key places. Definitely the corners of the buildings and around all openings like doors will be rebar inside and filled with concrete. As far as stress cracks? None.
Nice design, there is a product on the market called by several names,
one name is Sure-Wall, another name is EZ-Wall and I believe another is
Block Bond. All three have fiberglass in the mix. I know there is a
cinder block on the market that has a interlocking upside down "V" and
all you have to do is stack them and put 1/4" skim coat on both sides
and you've got a house in no time and they are unbelieveably strong.

I have completed. (see the MojaveJeff photo album) The first photo is of
3 stacked lego-type blocks. My thinking was to see if I could make a
good form to create some tight fitting, interlocking blocks that may not
need to be mortered. It worked out pretty well. However, I still go back
and forth in my mind as to the benefits of slip-forming walls versus
blocks and morter. Regarding compressing the blocks, I went the
ultracheap and slow way and used a sledgehammer after each 5 gallon
bucket's worth of papercrete to compress the mix.

erected between my air conditioner and my bedroom window to reduce the
noice so I could get some sleep. I used chicken wire over the raw wall,
then papercreted it with the same mixture and then painted.

with a 5-gallon bucket and a half-inch hand-drill.
