2021year7month30day The European steel industry produces about 70 million tons/year of steel by the electric arc furnace (EAF). The slag consists of about 15% by weight of the produced steel, thus from the perspective of the circular economy, it has a high potential as a co-product. This research aims to assess an innovative reuse of EAF slag as filler in

2003year1month1day Compared with steel slag (Table 2), the contents of CaO, Al 2 O 3, MgO and MnO in AOD slag are close to those in steel slag, but SiO 2 is much higher than in steel slag. Therefore, the basicity of AOD slag is lower than steel slag. Moreover, AOD slag contains much less iron than steel slag. Hence recovery of iron from AOD slag is not
