an insulation layer for my radiant floor. (First an 11/2" papercrete,

inches of Darjit to finish the floor) Right now I just have the
papercrete and I find it dusts all the time and scratches very easy. I
don't think it would work for a garage floor because it wouldn't be
able to support a lot of weight. Darjit would be strong and would work
great and it's made from recycled material. There is an example of a
floor on the architectural page of www.darjit.net.

FYI, as far as I can tell, Darjit is simply a different recipe of
papercrete. We have folks here who use rock dust and clay in different
combinations in their recipes. And papercrete could easily be defined
as a composite material made up of paper, water, aggregates and
binders. The binders can be clay, cement, lime, etc. The aggregates
can be sand, rock dust (if quartz, then simply smaller grains of
sand), perlite, vermiculite, etc.

So you could accomplish the goal of having a PC floor by simply
increasing the binders and aggregates. A "rich" PC with 50 percent
concrete, 15 percent clay and 10 percent rock dust would probably do
the trick.

Obviously, YMMV and it definitely depends on what materials you have
near you and at what cost. If Darjit has to be shipped from overseas,
there is both a economic as well as a environmental cost associated to
that.
