[Cob] official psi samples

[Damon Howell]

Janet,
	I greatly appreciate what you're doing. All this code talk may bore  
some people, but I see it as absolutely necessary that we get  
approval for every building we erect with cob or we're just blowing  
in the wind (not the exact phrase that came to mind). So, about the  
samples; you said they're "official," does that mean they will be  
tested using the same machine they test concrete with? What we need  
is actual numbers for when it fails during any given test. Someone  
done the seismic test (University of British Columbia I believe), but  
I be ____ if I can't find the results which would be pretty darn  
useful to all of us! I would like to believe that the strength of  
concrete is overkill for most residential buildings. We generally  
don't need such compressive resistance (depends on the design, of  
course). I looked at the photos on Kevin McCabe's site and noticed  
that all his interior walls are cob, which distributes the weight of  
the roof across a bigger footprint.
