“…The use of BOF slag and the feasibility of BFD use as fine aggregate resulted useful for partially replacing conventional aggregates in road paving. Finally, waste foundry sand and BF steel slag have been tested in an Indian study for gradation, specific gravity, morphology, chemical composition and compaction as well as engineering properties, shear strength and permeability [74]. In addition, compaction behaviour of these analysed by-products has resulted to be similar to granular soils and they have been tested for fill applications.…”

Over the last few decades, the European steel industry has focused its efforts on the improvement of by-product recovery and quality, based not only on existing technologies, but also on the development of innovative sustainable solutions. These activities have led the steel industry to save natural resources and to reduce its environmental impact, resulting in being closer to its “zero-waste” goal. In addition, the concept of Circular Economy has been recently strongly emphasised at a European level. The opportunity is perceived of improving the environmental sustainability of the steel production by saving primary raw materials and costs related to by-products and waste landfilling. The aim of this review paper was to analyse the most recent results on the reuse and recycling of by-products of the steelmaking cycles as well as on the exploitation of by-products from other activities outside the steel production cycle, such as alternative carbon sources (e.g., biomasses and plastics). The most relevant results are identified and a global vision of the state-of-the-art is extracted, in order to provide a comprehensive overview of the main outcomes achieved by the European steel industry and of the ongoing or potential synergies with other industrial sectors.

“…Conversely, the mechanical properties of combined CS and CKDstabilized soil were better than those of CKD and CS-stabilized soil. Kumar et al (2019) studied the characteristics of waste foundry sand (WFS) and blast furnace steel slag (BFSS) and found them better than conventional ll materials. Janalizadeh et al (2019) used the ultrasonic pulse velocity method to study the effect of copper sludge on cemented clay.…”

This experimental research has been conducted to improve the mechanical properties of the problematic expansive soil using copper slag. The copper slag has been utilized to improve the Talab soil in Nainwa for the rst time. These mechanical properties are consistency limits, compaction, and strength properties. The swelling properties show that the collected soil has a high degree of expansive nature and low speci c gravity. Therefore, the copper slag has been added to the soil from 5-30% at a 5% variation by its oven-dry weight. The experimental results reveal that the free swell index of soil has decreased by 69.88% with the addition of 30% copper slag. It has also been observed that the liquid and plastic limits have been decreased. The plastic limit of soil decreases because copper slag takes place in voids. Due to this phenomenon, the maximum dry density of soil has been increased by 14.75% with the addition of 25% copper slag. The California bearing ratio (CBR) value of soil has been increased to 1.13% (soaked condition) and 3.8% (unsoaked condition) by adding 25% copper slag. This research introduces an empirical relationship between unsoaked and soaked CBR with a determination coe cient (R 2 ) of 0.8254. Moreover, it has been observed that the uncon ned compressive strength of soil has increased by 51.68% with the addition of 25% copper slag. Moreover, the value of R 2 for the experimental results obtained in this research is higher than the published experimental results, presenting the experimental study's accuracy and reliability. In addition, the analysis of variance (ANOVA) test accepts the research hypothesis for the present investigation.
