“…The main by-products of the steel industry, blast furnace (BF) slag and steel-making (SM) slag, can partially replace cement in concrete because of its potential hydraulicity [1,2,4,5,6,7,8,9]. According to previous studies, about 70% of the total production of BF slag has been used as a replacement for Portland cement due to its numerous advantages, e.g., an increase in long-term strength and durability, decreased heat of hydration and the occurrence of the alkali-aggregate reaction.…”

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 steel-making slag has relatively low hydraulicity and a problem with volumetric expansion. However, as the quenching process of slag has improved recently and the steel making process is specifically separated, the properties of steel-making slag has also improved. In this context, there is a need to find a method for recycling steel-making slag as a more highly valued material, such as its potential use as an admixture in concrete. Therefore, in order to confirm the possibility of using electric arc furnace (EAF) oxidizing slag as a binder, a comparative assessment of the mechanical properties of concrete containing electric arc furnace oxidizing slag, steel-making slag, and granulated blast furnace (GBF) slag was performed. The initial and final setting, shrinkage, compressive and split-cylinder tensile strength of the slag concretes were measured. It was found that replacing cement with EAF oxidizing slag delayed the hydration reaction at early ages, with no significant problems in setting time, shrinkage or strength development found.

“…Particularly, its use in clinker production is emphasized, as an aggregate in structural concrete and mortar, whose applications are well-known and documented. Recent research also address the advantages of using steel slag as a partial replacement to coarse aggregate in concrete for effective gamma shielding [18]. This study investigates the application of steel slag in road construction for two primary reasons: first, road building, as compared to other sub-disciplines of civil engineering, is the largest consumer of natural resources, where steel slag can maximize their preservation; and second, sustainable recycling, that uncovers new material substitutes and their impact on the environment, is essential for road construction materials as pavements and embankment structures are in direct contact with the surrounding soil and potential pollution can infiltrate the groundwater [19].…”

Steel slag is a by-product in the production of steel. An increase of its production results in more landfills. It is mostly used as a building material in the construction of roads, where it substitutes natural materials. The use of steel slag in road construction has multiple benefits; both by solving the challenges of waste disposal and preserving environmental resources by moderating the consumption of non-renewable and natural aggregates. Apart from being used as a building material, steel slag is also used in numerous environmental applications, such as soil and water remediation and CO2 sequestration. However, a multidisciplinary environmental impact study of steel slag, particularly regarding both the aquatic and terrestrial organisms, is lacking. Steel slag contains traces of potentially harmful elements that endanger these living organisms, including heavy metals released into the environment. A high pH value can also significantly influence their leaching properties, thereby affecting the organisms in the water and soil. Given the widespread utility of steel slag, it is recommended to make a thorough risk assessment associated with the various environmental applications of this material.

“…In concrete, corrosion occurs by microbes (producing inorganic/ organic acids) causing deterioration which degrades the components of concrete and it is a serious issue to be addressed [35]. Induction furnace steel slag has been utilized in concrete by our research team earlier [36] which reveals that it can be used as a partial replacement of natural coarse aggregate. This study aims to provide antibacterial property of induction furnace steel slag on M. luteus, B. subtilis and S. aureus which can be a significant research data in the building environment of concrete constructions under microbial environment, thereby contributing to the sustainable constructions.…”

Metals and metal oxide-based nanocomposites play a significant role over the control of microbes. In this study, antibacterial activity of iron oxide (Fe2O3) nanocomposites based on induction furnace (IF) steel slag has been carried out. IF steel slag is an industrial by-product generated from secondary steel manufacturing process and has various metal oxides which includes Al2O3 (7.89%), MnO (5.06), CaO (1.49%) and specifically Fe2O3 (14.30%) in higher content along with metalloid SiO2 (66.42). Antibacterial activity of iron oxide nanocomposites has been revealed on bacterial species such as Micrococcus luteus, Bacillus subtilis and Staphylococcus aureus. Micrococcus luteus has undergone maximum zone of inhibition (ZOI) of 12 mm for 10 mg/mL concentration of steel slag iron oxide nanocomposite. Growth inhibitory kinetics of bacterial species has been studied using ELISA microplate reader at 660 nm by varying the concentration of steel slag iron oxide nanocomposites. The results illustrate that IF steel slag is a potential material and can be utilized in building materials to increase the resistance against biodeterioration. Graphic abstract
