RE: [papercreters] What to test for?

What about usage catagories.

Subject: [papercreters] What to test for?

 

I'm all for testing everything we can. The more we can quantify and
understand about each different recipe or construction method the
better.

That said. We should prioritize what numbers are most important for
us to get first. It is unlikely we will be able to create a testing
utopia overnight.

From what I've read and observed subjectively, the following
parameters appear to be of most interest to inspectors:

Compressive Strength
Insulation R-Value
Fire resistance/combustibility
Smoke generating capacity
Mold resistance
Insect (termite & carpenter ant) resistance

The following parameters will also be helpful to those making and
using papercrete:

Density
Wet slurry viscosity and/or slump.
Wet slurry adhesion (very helpful when wanting to use papercrete
as plaster or stucco)

The following parameters would also be nice to know but have a lower
priority at the moment:

Tensile Strength
Shear Strength

Impact resistance (storm debris) (gotta test this if only to
have an excuse to build an air cannon!)

Moisture Content (measured as papercrete is made, and measured
long term inside walls of completed structures)

Did I miss anything?
