Abstract: In order to use electric furnace ferronickel slag (FNS) safely and efficiently, the composition and suitable application of typical FNS sand and FNS powder were analyzed by means of XRF, XRD, SEM-EDS, TG, FTIR and laser particle size analyzer. The results show that, there are more amorphous phases in the surface of FNS sand. MgO in FNS exists in two forms, one is mineral crystalline phase in large size FNS sand, the another one is amorphous phases in small size FNS sand. The use of FNS sand can be classified according to its particle size: the large size FNS can be used to replace part of sand, while the small size FNS can be ground and used as concrete admixture. Due to the existence of air pores, the crushing value of FNS sand decreases with the increase of particle size. In addition, the content of Cr element in small FNS powder is less than that of other particles, while the distribution of other elements in FNS is not obvious. The presence of a small amount of carbonate in FNS powder may affect the composition of cement hydration products.
