Re: Concrete Additives



I wish the company you are assisting was local.  If you have any
pharmaceutical type companies, (e.g. wound dressing/surgical supply
manufacturers) in your area) there is a scrap waste stream of wound
dressing material left over after product manufacturing.  While
lightweight, these materials also add strength.  Maybe this material is
an option as an additive.  Please let me know if this is applicable in
your area.

P2 purists please feel free to skip this message. We were recently
contacted by a company looking for ideas for a fibrous material that
could
be added to the mix for a lightweight concrete. They were considering
shredded fabric (sans zippers, buttons, etc.) as a possibility and had
also
considered straw.  Major consideration was being given to reuse of a
material that is readily available locally. We put them in contact
with
local thrift stores and recycling organizations but thought the
collective
mind might have some more creative solutions. Thanks for any ideas you
could pass on.
