This study investigated the possibility of using electric-arc furnace dust (EAFD) as an acidic soil amendment. The experiments were conducted using incubation and pot experiments. In the incubation experiment, various rates of EAFD were added to an acidic soil and properties such as pH; electrical conductivity of the saturation extract (ECse); and available phosphorus (P), potassium (K), iron (...

Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

Electric arc furnace baghouse dust (EAFD), a waste by-product of the steelmaking process, contains the elements that are volatilized from the charge during the melting (Cr, Pb, Zn, Cu and Cd). The results of leaching tests show that the concentration of these elements exceeds the regulatory limits. Consequently, EAFD cannot be disposed of in ordinary landfill sites without stabilization of the ...

This paper reports the method and mechanism for improving the strength of marl and desert sand utilizing electric arc furnace dust (EAFD), an industrial by-product, in lieu of cement or lime. EAFD was used in conjunction with a small quantity (2%) of cement. The mechanical properties and durability characteristics of marl and sand mixed with 2% cement plus 5-, 10-, 20- or 30%-EAFD, by weight of...

This study investigated electric arc furnace dust (EAFD) reuse as a raw material in concrete mixes. A comprehensive experimental program consisting of two phases of testing was carried out. The first phase included the replacement of ordinary Portland (Type I) cement by unsieved dust with the percentages of 0, 2.5, 5, 7.5 and 10%. The second phase included the replacement of quartz (filler) by ...

Introduction Zn-containing electric arc furnace dust (EAFD), a solid waste produced during steelmaking process, contains many valuable metals, such as Fe, Zn, Mn, Ca, etc. (Kukurugya et al., 2015; Wang et al., 2016b). And the dust is classified as hazardous wastes according to the US Environmental Protection Agency because of the presence of Cr, Pb, etc. (Ann M. Hagni et al., 1991; Wang et al.,...

BACKGROUND As a result of the previous part of this trial, many patients with cardiovascular disease were expected to receive a statin for the first time. In order to provide these patients with comprehensive information on statins, as recommended by professional guidance, education at first and second dispensing of statins had to be implemented. This study was designed to assess the effectiven...

Electric arc furnace slag (EAFS) and electric dust (EAFD) are the waste materials from steel production by EAF route which implies remelting of iron scrap in furnaces (EAF). In recent years, special attention is paid on valorisation EAFS EAFD since disposing both may cause negative impacts environment. this paper, methods that use to process have been reviewed, their advantages disadvantages al...

This paper reveals an appropriate ingredient to operating the hazardous and radioactive electric arc furnace dust (EAFD) from steel production factory using cement immobilization technique. The specimens were prepared by mixing tap water with binders (i.e., ordinary Portland cement: OPC, EAFD) at different EAFD replacement of 0%, 15%, 25%, 35%, 40%, 45%, 50% weight. water-to-binders ratio was f...
