APPLICATION OF ELECTRIC ARC FURNACE SLAG

Steel making process in electric arc furnaces generates up to 15 % of slag, which is, based on its properties, classified as non-hazardous waste. Disposal of such material requires large surfaces and it is rather unfavourable in economical terms. Therefore, researches have been conducted to establish the potential use of slag in different activities. Slag samples were taken from the non-hazardous land fill run by the Tube Rolling Mill in Sisak and the analyses conducted in cooperation with the Faculty of Agronomy and the Croatian Institute of Civil Engineering, both in Zagreb, have shown that slag can be used for agricultural purposes as inorganic soil enhance, in construction industry as an additive to cement and in civil engineering as an additive for road construction.
