Sand Additives includes Seacoal,
Coal Tar Pitch, Gilsonite and Blown Asphalt. The theories involved in
sand additives are Gaseous Cushion Theory, Lustrous Carbon Theory and
Reducing Atmosphere Theory.
Sand Additives are used for
Construction, Metal Casting, Soil Blending, Land Applications,
Composting, Backfill and Pipe Bedding.
Major markets are metallurgical,
glass and construction, accounting for 92.6% of total sales. The
metallurgical sector can be subdivided into foundry sands and steel
applications, fluxing (non-ferrous), refractories and silicon
manufacture. Major markets for fume silica are construction (cement and
concrete additives); whilst the ceramic industry is the largest consumer
of milled silica.
Commercial soil blending operations
can use foundry sand to produce horticultural soils, topsoil, potting
soil, and turf mixes. These soil products are typically mixtures of sand
or gravel with peat, fertilizers, and/or top soil. Foundry sand can also
improve the performance of agricultural soils, and can be used as a
composting ingredient.
Foundry sand can be used as a cover
for the working face of an active landfill, for road construction within
the active cell, or as a substitute for virgin aggregate in the
construction of drainage layers for landfill leachate collection
systems.
The foundry industry has frequently
cited the beneficial reuse of foundry sand as one of its most important
environmental issues.
The U.S. foundry industry
uses approximately 100 million tons of sand per year. Roughly 90 percent
is reused for making molds within the foundries, but 9 to 13 million
tons of this sand is no longer useable in the casting process. Of this
sand, approximately one million tons are recycled for other uses every
year; the remaining 8 to 12 milliLustrous Carbon Theory tons are
landfilled.
Foundry sand can be obtained
directly from foundries, most of which are located in Midwestern states,
including Illinois, Wisconsin, Michigan, Ohio, and Pennsylvania.
Spend foundry sand has low
absorption and is nonplastic. Reported values of absorption were found
to vary widely, which can also be attributed to the presence of binders
and additives.
