The electric arc furnace (EAF) has the potential to significantly contribute decarbonization of iron and steel industry. However, during EAF steelmaking, carbon still needs be injected into molten slag initiate foaming, which is beneficial energy efficiency protection furnace. To move away from fossil carbon, biocarbon gained attention as an injection agent. In this study, two biochar candidate...

Temperature control is the primary concern during design and construction process of mass concrete structures. As production has an enormous negative environmental impact, development green concretes will eventually become as important thermal characteristics. Therefore, this paper investigates use Electric Arc Furnace (EAF) steel slag aggregate for partial replacement natural in concrete. The ...

The aim of this study was to investigate if electric arc furnace (EAF) slag generated during steel production could have an application as a soil enhancer in agriculture. For that purpose, greenhouse experiment conducted on common beans (Phaseolus vulgaris) cultivated enriched with EAF (at 1% and 2% level), synthetic fertilizer (NPK), combined fertilizer, or control (untreated) soil. were expos...

Waelz slag is an iron-containing waste generated during electric arc furnace (EAF) dust processing in a rotary kiln named the process. This study focuses on reduction smelting of to produce iron-based alloy. The thermodynamic simulation using FactSage 8.0 software was carried out predict temperatures metal and obtained as well their compositions. Based results, experiments were performed labora...

This study quantifies the potential environmental benefits associated with incorporation of industrial by-products and recycled materials combined warm mix asphalt (WMA) additives in wearing course mixtures for pavement construction. An electric arc furnace (EAF) steel slag-based three incorporating slag fractionated reclaimed (RA) varying contents (i.e. 25, 40, 50%) were analyzed comparatively...

Electric Arc Furnace (EAF) slag can be reused as aggregate in Portland cement concrete mixes. The addition of EAFS and other waste co-products (fly ash, blast furnace slag) will modify the binding properties will, importantly, enhance global sustainability such concretes. These mix designs offer acceptable pumpability self-compaction fresh state reinforced with fibers. In this study, eight diff...

Electric arc furnace (EAF) steel bottom-blowing can effectively improve the temperature and composition uniformity of molten pool during smelting process. To explore effect molten-steel characteristics on at various stages smelting, we divided process EAF into four stages: melting stage, early decarburization intermediate ending stage. The numerical simulation software ANSYS Fluent 18.2 was use...
