The granulation through (quenching), electric arc furnace slag (slag refining oxidizing and reducing) acquire glassy structure (amorphous), stabilizing expansive properties and can be used as an addition to cement, plus allow significant recovery of the metal phase. Also the

An Electric arc furnace (EAF) produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added (as flux) combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.

Industrial waste products can be considered as renewable resources. Steel industry wastes have a severe impact on the environment whereas this industry involves a myriad of operations which create vast volumes of air emissions, liquid effluents, and solid wastes. This study presents the feasibility of using Electric Arc Furnace Dust (EAFD) as a cement replacement material (CRM) in comparison

Keywords: Steel Slag, Limestone, Concrete, Aggregate Two common methods are used in steel production as basic oxygen furnace and electric arc furnace1. Electric arc furnace is used more than 40% of global steel production in the world because scrap recycling is more economical and sustainable production1-3.

For sustainable development in the construction industry, blast furnace slag has been used as a substitute for cement in concrete. In contrast, steel-making slag, the second largest by-product in the steel industry, is mostly used as a filler material in embankment construction. This is because stee

Oct 01,  · The electric arc furnace slag generally used as a substitute for natural aggregate in concrete is sharp-cornered with a honeycombed surface texture. This characteristic can be useful to develop very strong interlocking properties [26] .

Linz-Donawitz (LD) slag, solid waste produced during steel manufacture in basic oxygen furnace, is difficult when it comes to handling and disposal and has very limited utilization. To increase its reusability, the suitability of supplanting cement with LD slag in concrete was examined. To study the impact of partially replacing cement with LD slag on strength, microstructure, and durability

satisfied the requirements for rutting [1] [53]. Steel slag also showed noticeable improvement in resistance to permanent deformities as well as increased resilient modulus [3] [27]. Blast furnace and electric arc steel slag from research is very efficient in control of storm water for flood prone regions [34].

More sustainable mortars and concrete with used furnace slag as an aggregate. "The thermal conductivity of sand extracted from electric arc furnaces is low, making it a good option for
