Hi ALL

The dust that is spoken of is air born gravel pit dust, No chemicals =
have been added at this point.

-------------------------------------------------------------------------=
-------
 =20
Subject: Augmentation to, or the replacement of CLAY as a component of =
COB, or UNFIRED EARTHEN MASONRY.=20

I propose that the Dust that is washed by air scrubbers at a Nonmetallic =
Mineral Processing Plant, such as in an Asphalt or Concrete Plant, be =
used to augment or replace the clay component in COB or UNFIRED EARTH =
MASONRY construction.=20

Date April 8, 2002

-------------------------------------------------------------------------=
-------

I work for a road construction company, and in the course of my work I =
have to hull this fugitive dust to the land fill. At the asphalt plant =
they use air scrubbers to eliminate the air born dust problem. The water =
is pumped through a settling tank before it is recycled through the =
system. When the tank reaches it's capacity we hull the mud to the land =
fill.

The consistency of this material is more like pug mill ground clay.

After hulling my first batch, I did not get the dump truck box cleaned =
out well enough.

And the heat from the asphalt baked the clay as hard as concrete. It was =
the rest of the year before I got the stuff scraped out. It bonded to =
the smooth steel sides of the box as though it were epoxy.

I just thought of a variable in the process. And that would be the type =
of rock used in the making of asphalt. We use "red rock" in our mix, It =
is crushed RED GRANITE. And also"BA" kinda like "Class 5 Gravel". 40% to =
60% ratio

Air born dust is still dust. But the kind of material it comes from and =
what percentages, may be of importance.

-------------------------------------------------------------------------=
-------

If you NEED a clay, this stuff should be FREE. Or the price of shipping.

Thank you for giving my ideas some thought.
