Cob: Re: Pharaohs Concrete

[Arlie Haig]

Hi,
I just saw a bit on TV where, on the Great Wall in China, some grout holding
bricks together was still doing it's thing whereas the brick had eroded
away. An analysis of the grout revealed it was made from sand, lime and rice
flour.
I'm gonna try it.

Little odd name but does explain an alternative concrete which may be
obtained from a nearly free source.
I would question this before doing anything. This site is way out there on
the edge sometimes.
