Around 70% of the world's steel production depends on the blast furnace process (integral route), as the availability of scrap limits electric arc furnace production to 30% of global demand . In the BOF process, the amount of BOF slag produced ranges between 0.1 and 0.2 tonnes per tonne of steel produced [3,4].

Conclusions. The characteristics of a construction material made from waste steel slag were investigated in this research. Bricks with a steel slag addition of less than 10% and a firing temperature above 1050 °C would fit CNS 3319 third-class brick for builders. An appropriate addition of steel slag would reduce the firing temperature needed.
