Abstract

The technological properties and the electromagnetic shielding efficiency of clay based ceramic building products prepared by using electric arc furnace slag (EAFS) and ladle furnace slag (LFS) as admixtures and fired at various temperatures were investigated. Chemical and mineralogical analyses were performed to characterise EAFS and LFS. The results showed that the ceramic specimens prepared by the addition of EAFS to the clayey material presented better shielding efficiency than the relevant of LFS, both tested in the same X-band frequency range (8–12 GHz). The prepared specimens showed water absorption, flexural and compressive strengths and firing shrinkage within accepted limits. Modulus of rupture and compressive strength values were slightly decreased by increasing the addition of EAFS and LFS. The technological characteristics were found to be affected by both the percentage of EAFS and LFS added as well as their grain size. Finally, the leaching test performed showed stabilisation of all studied toxic elements within the sintered ceramic structure.
