High performance concrete with electric arc furnace slag as aggregate: Mechanical and durability properties

Characterisation of electric arc furnace slags as concrete aggregate in a small island developing state: A preliminary study

“…1), it can be observed that it is made of angular particles. This angular feature aids in creating very strong interlocking bonds when mixed with cement [44] and is in line with the findings of Faleschini et al [24] and Qasrawi et al [25] who wrote that the shape and texture of EAF slag has a positive effect on the compressive and tensile strength of concrete owing to the bonds formed with cement. Besides, BDS is less porous compared to LPS which implies that its water absorption will be less, a criteria that is deemed important in assessing the performance of aggregates in concrete.…”

“…Luxán et al [9] clarified that there are two types of slags produced from EAF; the black basic slag from the cold loading of scrap and white basic slag produced during the fining stage while Kuo et al [10] wrote that EAF slag can be classified into EAF oxidising slag and EAF reductive slag. Several studies dealt with the characterisation of EAF slags as it is [9,11,12] and pre-treated [13][14][15] to be consequently used in civil works namely as aggregates in concrete [16][17][18][19][20][21][22][23][24][25][26][27], asphalt mixtures [28][29][30][31][32], hydraulic concrete [33], sub-base material in flexible pavement [34][35][36], low energy belite cement [37], high performance concrete [24], reinforced concrete beams [38], thin skid-resistant surfacing [39], road construction [40], bituminous paving mixtures [41] and blended cement pastes [14] with promising results. Since most studies have been carried out in developing and developed countries and concentrated mainly on black basic slag, this research is the first preliminary attempt at characterising the two types of EAF slags from the recycling of scrap metals in a small island developing state (SIDS) with Mauritius as a case study so as to assess its suitability as a replacement of aggregates in cement-based materials.…”

A Feasibility Study on the Application of Basic Oxygen Furnace (BOF) Steel Slag for Railway Ballast Material

“…Namely, BF iron slag (air cooled BF slag and granulated BF slag) has long been utilized as a construction material (aggregate and concrete binder etc. ), and steel slag (BOF slag and EAF oxidizing slag) has been the subject of numerous research efforts with the aim of used as aggregates for road, embankment, reinforced concrete elements, or high-performance concrete with good bond with reinforcements, eco-friendly prestressed concrete sleeper [1][2][3][4]. However, steel slag still has not been widely utilized as aggregate for concrete production limited by Construction Specification, due to its unqualified properties with the specification.…”

Performing self-compacting concrete with electric arc-furnace slag as aggregates

“…of EAF slag are generated every year, which this research group is convinced can be turned into a useful by-product, investing it with added value. Due to its physical and chemical properties, many researchers have proposed its use as an aggregate in hydraulic and bituminous mixes [3][4][5][6].…”
