Cob: putting stones in wall > Urbanite

[Charmaine R Taylor]

Hi Randy,  broken concrete rock is  often called "Urbanite" these days, used as a building material, usually for foundation or floor, paths, etc.  If the wall was all urbanite you'd have a stonehouse.  Rocks don't respire ( maybe too slow for us to notice) but the
mortar would, if it was a lime mortar, not a pure cement mortar.  People with lots of freestones or field stone build slipform walls of stone and mortar, you could too.
