Waste recycling and reuse is an important component of sustainability. Extensive research is being conducted to address this issue by incorporating industrial by-product such as steel slag, copper slag, fly ash, ferro-chrome slag, and so on into the construction industry. Steel slag, which is mostly calcium carbonate, is created as a …
Electric arc furnace (EAF) steel slag, generated from carbon steel production process, is the most interesting. from the asphalt technology point of view. This paper aims to explore the ...
Utilization of steel slag in construction industry as aggregate and cementitious material. for the applications toward bric ks production, asphalt mixes, radiation shielding concrete, ...
Iron slag has been used profusely in the construction industry, although steel slags are only partially consumed as a construction material due to its higher iron and calcium oxide content. However, steel slag has been found to have a high potential for several environmental applications due to its unique chemical properties.

The slag processor may also be required to satisfy moisture content criteria (e.g., limit the amount of moisture in the steel slag aggregate prior to shipment to a hot mix asphalt plant) and to adopt material handling (processing and stockpiling) practices similar to those used in the conventional aggregates industry to avoid potential segregation.
Abstract. In this review, steel slag usage in the cement and concrete industry and its environmental effects were examined. Also, its physical and chemical structure, its effect on the characteristics of concrete, and its applications in different usage areas were specified. Within the scope of the study, literature was examined by …
Therefore, stabilisation of slag through the hydration of CaO and MgO phases is needed before its use in construction. Naturally, this can take several months to stabilise when exposed to rain and sun. This aging process is time-consuming, restricting its usage within the construction industry.
The 2015 recovery quantities for blast furnace slag are shown in Fig. 15. Granulated slag makes up 86 %, of which almost the entire amount is used in the cement industry. The fields of application of the air-cooled slag are mainly in road construction and other uses in the construction industry. 4 Trends in slag recycling
The use of ladle furnace basic slag (LFS) as a cementitious material in industrial applications requires an in-depth knowledge of its characteristics.
