Properties of Blast Furnace Slag Cement Modified with Electric Arc Furnace Slag

Journal of the Korean Ceramic Society, 2006
Properties of slag cement that contained 50 wt% of blast furnace slag were studied when replaced blast furnace slag powder with electric arc furnace slag powder. Electric arc furnace slag was aged for about 2 months in the air by being crushed to be 1-3mm in size.

Leaching Kinetics of Iron from Electric Arc Furnace Slag (EAFS)

AIJR Proceedings, 2022
The steelmaking process produces a substantial amount of electric arc furnace slag (EAFS). Therefore, this present study conducted acid leaching, with and without the use of oxidants such as hydrogen peroxide (H2O2) and potassium permanganate (KMnO4), to increase the amount of iron (Fe) recovered from the EAFS.

CHARACTERIZATION OF ELECTRIC ARC FURNACE STEEL SLAG

2017
Steel production steelworks results also in large amounts of steel slag as a byproduct. [1-4] The resulting slag can be applied in different branches of the industry, depending on its properties and composition, which are tailored to the specific application requirements by additional procedures. Thermal stability of slag depends on its composition and

Valorization of electric arc furnace primary steelmaking slags for cement applications

Waste Management, 2015
To produce supplementary cementitious materials from electric arc furnace (EAF) slags, FeO was reduced using a two-stage reduction process that included an Al-dross reduction reaction followed by direct carbon reduction. A decrease in FeO was observed on tapping after the first-stage reduction, and further reduction with a stirred carbon rod in the ...

Environmental Impacts of Asphalt Mixes with Electric Arc Furnace Steel Slag

Journal of Environmental Quality, 2011
Electric arc furnace (EAF) steel slag can be used as an alternative high-quality material in road construction. Although asphalts with slag aggregates have been recognized as environmentally acceptable, there is a lack of data concerning the potential leaching of toxic Cr(VI) due to the highly alkaline media of EAF slag.

Properties of concretes with Black/Oxidizing Electric Arc Furnace slag aggregate

Cement and Concrete Composites, 2013
Abstract The aim of this work is to comprehensively investigate the possibility of partially substituting natural aggregates with Black/Oxidizing Electric Arc Furnace (EAF) slag in concrete production. Five recycled and one traditional mixes were produced to identify a convenient substitution ratio for the concrete.

Fiber Reinforced Concrete Manufactured with Electric Arc Furnace Slag

2017
The use of electric arc furnace slag (EAFS), a by-product of the steelmaking industry, as an aggregate in concrete has been demonstrated to be a good practice in its manufacture. Furthermore, the incorporation of fibers in concrete provides a more ductile behavior, increasing their tenacity and load capacity, improving the flexotraction strength and ...

Structural characteristics and cementitious behavior of basic oxygen furnace slag mud and electric arc furnace slag

Construction and Building Materials, 2019
Abstract Basic oxygen furnace (BOF) slag mud and electric arc furnace (EAF) slag were characterized by TG-DSC, XRD, FTIR, 27Al MAS-NMR and ICP-MS techniques to correlate structural characteristics with cementitious behavior. BOF slag mud is a by-product discharged after the wet milling and magnetic separation of basic oxygen furnace steel slag.

Use of Electric Arc Furnace Slag for High Strength Concrete Production

Applied Mechanics and Materials, 2016
In this paper the use of Electric Arc Furnace slag (EAF slag) for the production of High-Performances Concrete (HPC) is explored, as a fully replacement of the natural gravel. Several mixtures were produced, varying the water/cement ratio, the cement and the admixture content, with the aim of reaching a strength class between C50/60 and C60/75, and an ...
