Paper Title:
Pilot-Scale Reconstruction of Steel Slag with Electric Arc Furnace Slag and Coal Cinder
  Abstract

To realize the industrial application of online reconstruction technique of steel slag, a pilot-scale reconstruction research of steel slag (SS) with electric arc furnace slag (EAFS) and coal cinder (CC) and its mechanism were investigated. The results show that after reconstruction, the free-CaO content of reconstructed steel slag (RSS) is reduced. XRD analysis indicates that the reconstruction reaction can promote to create more active cementitious minerals (C2S, C3S, C6AF2 and C6A2F) in RSS. Composition adjusting materials formula composing of EAFS and CC at the ratio of 70:30 is optimum, which can meet the standard of the first grade steel slag powder according to Chinese National Standards GB/T 20491-2006.
