[Cob] Coblist Digest, Vol 10, Issue 52

[Jill Hogan]

I never use cement concrete in my buildings it is not compatable with 
earth. In all the houses we restore the worst damage is where cement has 
been used. What holds earth buildings togethere is the molecular 
structure of earth being platlets and the magnetic energy of moisture 
between those platlets. Cement sucks the moisture out and hey presto the 
wall turns to powder and of course collapses. I only use lime concrete 
and plasters as they have the same molecular structure as earth. There 
ius a natural flow of air and breathing which should never be blocked by 
artificial materials.
