[Cob] Stabilizing soil with cement

[dirtcheapbuilder-Charmaine Taylor]

Rodger- cement will only "coat" the particles, and not bind long term.  
    you need to use hydrated lime--  try 2-5% by volume and see how it 
holds up.  a chemical  bonding- agglomeration and flocculation occurs 
and can  permanently stabilize the soil you have.

do some testing and see how you like it.
