The chemical-mineralogical composition of steel-melting slags varies within wide ranges, and this is the major drawback for recycling (Krivenko, 1986). Alkali-activated cements made from basic steel-melting slags cured for 28 days in normal conditions show compressive strengths of 15–20 or 20–30 MPa when sodium carbonate or sodium di- and metasilicate are used as activators, respectively.

3. Chemical Composition of Steel Slags. Both BOF and EAF slags are formed during basic steelmaking operations, as explained above. Therefore, in general, the chemical and mineralogical compositions of BOF and EAF slags are similar. Calcium oxide and iron oxide are the two major chemical constituents of both EAF and BOF slags.

From the chemical/mineralogical composition, the aerosol complex refractive index was determined for several wavelengths from ultraviolet to near-infrared. Both real and imaginary parts show lower values for particles smaller than 500 nm in diameter (1.55–2.8 × 10 −3 i at 530 nm) and slightly higher values for larger particles (1.57–3.7 × 10 −3 i at 530 nm).
