Electric arc furnace granulated slag for sustainable

Abstract This paper deals with the use of industrial by-products from electric arc furnace (EAF) granulated slag for the partial replacement of natural aggregates commonly used to manufacture concrete. Three different gradings of EAF granulated slag were considered.

The Potential of Ladle Slag and Electric Arc Furnace Slag

The blast furnace (BF) iron slag, also known as a ground granulated blast furnace slag (GGBFS), the electric arc furnace carbon or stainless steel slag (EAF-C/S), and the ladle furnace basic slag (LS), also called the white slag, have been regarded as precursors which exhibit good mechanical properties following alkali activation and can be used to create valuable materials for building and civil

Performance of concrete containing Nigerian electric arc

01/09/2020 Nigerian electric arc furnace steel slag (EAFS) as industrial waste was used as coarse aggregate in concrete for the replacement of natural aggregate. Three sizes of 5/10, 5/14 and 5/19 mm of coarse aggregate at EAFS content of 0, 25, 50, 75 and 100% were considered. The EAFS aggregate morphology was characterised with X-ray computed tomography.

Ground granulated blast furnace slag (GGBS)

Ground granulated blast furnace slag (GGBS) GGBS is primarily a binder used as an addition to cement which uses the latent hydraulic properties of GGBS to produce Portland blastfurnace cement (6-35% of GGBS) or blastfurnace cement (36-90% GGBS) produced by blending at the concrete mixer, or as a factory blend at the cement factory.

Hydration characteristics of cement pastes incorporating

replacement of OPC with Electric Arc-Furnace steel slag or GGBS leads to a slow rate of formation of hydration products at early ages. However, at later ages, mixtures containing GGBS and waste slag produced more hydration products than the control OPC mix, especially when cured under a hot humid (Mediterranean) climate. The results suggest the viability of application of such industrial waste

Types of iron and steel slag : NIPPON SLAG ASSOCIATION

Electric arc furnace slag is generated when iron scrap is melted and refined. It consists of oxidizing slag that is generated during oxidation refining, and reducing slag that is generated during reduction refining. Approximately 70 kg of electric arc furnace oxidizing slag and 40 kg of reducing slag are generated for each ton of electric arc furnace steel.
