Possibility of Concrete Prepared with Steel Slag as Fine and Coarse Aggregates: A Preliminary Study

Utilization of Water-Cooled and Air-Cooled Slag Aggregate in Concrete: A Solution to the Secular Economy

“…Many researchers studied various waste and by-product materials that are available in the local market to find a proper substitute for natural aggregate while eliminating the transportation pollution and expenses [19,20]. For example, recycled concrete aggregate [21][22][23][24][25][26][27], recycled tires [28][29][30][31][32], post-consumer glass [33][34][35][36], recycled plastic [37][38][39], and steel by-product aggregate have been suggested a replacement for fine or coarse aggregate [40][41][42][43][44][45][46][47]. Steel slag aggregate, a by-product of the steel manufacturing process, is another possibility.…”

“…Few researchers studied the effect of using both WCS and ACS combined in concrete instead of natural sand and dolomite as a fine and coarse aggregate replacement, and the results showed the possibility of partial or full replacement of natural aggregates by steel slag aggregates with comparable features to traditional concrete [40][41][42]66].…”

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

“…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.…”

Feasibility of making Concrete with Iron Slag Scrap as Coarse Aggregate

“…Nowadays, slag is still used to build roads. However, use of slag is not limited to roads anymore, but slag aggregates are widely used in all kinds of civil works [6,7]. In general, properties of iron and steel slag aggregates are comparable with that of natural aggregate.…”
