“…The study also showed that the use of ground FNS as part of the binder similar water demand as for the control mix. Similarly, Katsiotis et al (2015) concluded that the presence of FNS slowed down the hydration process and the strength development in FNS blended concrete. In addition, the authors reported an increase of compressive strength at later stages of curing due to the effect pozzolanic reaction of FNS.…”

“…The manufacture of one tonne of ferronickel alloy discharges around four tonnes of FNS, which is described as an amorphous material due to the cooling process in water. Katsiotis et al (2015) studied the hydration process and the leachability of blended cement containing ground FNS. Importantly, the heavy metal concentrations in leachates from FNS specimens were below the limits proposed by the United States Environmental Protection Agency (EPA).…”

“…As a result, FNS is classified as non-hazardous waste and is suitable for use in the construction industry. FNS has also been categorized as non-hazardous waste according to the European Catalogue for Hazardous Wastes (Katsiotis et al 2015;Dourdounis et al 2004;Lemonis et al 2015). The non-hazardous characteristic of FNS provides opportunities to develop new applications for FNS in the construction industry allowing recycling this industrial by-product and reducing the consumption of natural resources such as natural sand.…”
