Recycling of Malaysia’s electric arc furnace (EAF) slag

01.12.2014· Malaysia's EAF slag waste is recycled into value-added green ceramic tile. As opposed to electric arc furnace (EAF) slag, blast furnace (BF) slag has been successfully utilized for ceramic tile due to its low iron oxide content (0.5–1.5 wt.%) (Ghosh et al., 2002). Unfortunately, the high iron oxide content in EAF slag (30–34 wt.%) tends to reduce densification range of ceramic tile

Comparing Properties of Concrete Containing Electric Arc

Electric arc furnace (EAF) slag, one of the SM slags, is produced by refining the process of recycled steel scrap in the electric arc furnace. The main chemical characteristics of EAF slag are its high free calcium oxide (free-CaO) and Fe oxide content. It has been reported that these two compounds cause the volumetric instability of EAF slag.
