摘要：
Ladle furnace slag (LFS) is a solid waste by-product from the secondary stage of steel making process in ladle refining furnace. An extensive suite of engineering and geotechnical tests was undertaken on LFS aggregates to evaluate its potential to use as a road construction material. The chemical composition and microstructure of LFS samples were evaluated using X-ray fluorescence analysis (XRF) and scanning electron microscopy (SEM). The effect of different curing regimes on the strength of unbound LFS was also investigated. It was found that both duration and temperature of the curing had a vital role in the strength development of LFS samples, which could be attributed to the relatively high lime content of the LFS material. The suitable engineering properties of LFS materials could make it a reliable substitute for quarry produced pavement materials, which may result in diverting large amount of LFS from landfills.
