Steel slag's usage is related to its physicochemical characteristics. The density of steel slag is g/cm 3. Steel slag is hard because of its high Fe amount and is highly resistant to corrosion. The grindability index of steel slag is [38]. Steel slag primarily consists of SiO 2, CaO, Fe 2 O 3, FeO, Al 2 O 3, MgO, MnO, and P 2 O 5 ...

Steel slag is a mixture of metal oxides and silicon dioxide and may contain metal sulphide along with metal in the elemental form. Steel slag output is approximately 20% by mass of the crude steel output [ 1 ]. It is found that over 2000 years ago during the times of Roman Empire, slag was used in building roads.

In the process of making steel, around 10%15% of slag is produced. In the last decade, several studies have proposed the application of steel slag as geomaterial. However, its potential application as a subgrade material in river embankments (artificial banks to protect the adjacent land against flooding) has been unexplored hitherto.

Traditionally, steel mill slag yards have been designed and built with the idea that slags are waste products, and the slag yard is only a dump, not only for slags, but also for a variety of other wastes generated at many points in the steel mill. For example, at the Cherepovets Works, the "slag" accumulations contain, on the average, about ...

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel ...

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste footprint.
