ASH AS A RECOVERABLE RESOURCE
equipo ST & tecnoloxía (STET) develops and manufactures Triboelectrostatic Separators that provide a high rate and completely dry beneficiation for pulverized coal fly ash. The STET separation process has been used commercially since 1995 para carbón pulverizado (PC) fly ash beneficiation and has generated over 20 millón de toneladas de alta calidade cinzas para a produción de formigón.
Controlado ProAsh® baixo Loi é actualmente producido coa tecnoloxía de STET na 12 estacións de enerxía nos Estados Unidos, Canadá, o Reino Unido, Polonia, ea República de Corea. ProAsh® fly ash has been approved for use by more than 20 autoridades de estradas estatais, así como moitas outras axencias de especificación. ProAsh® tamén foi certificado por Canadian Standards Association e UNE 450:2005 estándares de calidade en Europa.
equipo ST & Technology was chosen as a key supplier in the construction of the New World Trade Center and produced thousands of tons of high-quality fly ash, creación de formigón con alta resistencia, durabilidade, workability, and reduced heat of hydration.

Fly Ash is a byproduct produced from burning pulverized coal in electric power generating plants. Its chemical components vary, but most often include oxides of silicon (SiO2), aluminum (Al2O3), iron and calcium (CaO).
The primary question surrounding fly ash is what to do with it. Disposing of Fly Ash has its issues. Most of it is dumped in holding lagoons or landfills. Because Fly Ash contains heavy metals there is a concern that it could leach into the soil or escape into the air if the lagoons rupture. Afortunadamente, Fly Ash is a pozzolan, which is a material that serves as a cement when mixed with lime and water. Recycled Fly Ash has several industrial uses; as the prime material in asphalt, ladrillos, blocks, tintas, tiles and backfill. Because it reacts chemically with calcium hydroxide which is released when cement and water are mixed the most noteworthy use is as a replacement for Portland cement in concrete. Recycled Fly Ash is an environmentally friendly product used to improve the strength of concrete.
Fly Ash uses less water than Portland cement, thus it is easier to use in cold weather. Additional benefits to using Fly Ash as a replacement of Portland cement are:
