Abstract:
Purpose.The aim of our research consists in argumentation of the possibility of transformation of slag from potential pollutants into a new material used and its promotion as an alternative raw material for the production of consumable layers of asphalt concrete for highway.
Methodology.The research on the possibility of using the slag of the electric furnace in Ferronickel Foundery is based on the practice of CISRO and Sumitomo Metals Industri in Japan, while the products of this process, in accordance with the standards EN12697-1:2006, EN12697-23, EN12697-12, EN 12697-27 dhe DD226-26/2004, have been used as aggregates for the production of asphalt concrete in the AHN Group-Kosovo.
Findings.This paper presents the results from a study program related to minimizing the pollution impact of Fe-Ni slag landfill in Drenas, through valorization and improvement of physical-mechanical properties of slag according to the method of integrated dry granulation and using it afterwards as aggregate for the production of AC11 surf.
Originality.Laboratory analyses were conducted in specialized laboratory and data presented are achieved through the use of devices and equipment that are necessary for experimental research, thus the obtained results are original data presented in this paper.
Practical value.From the research data it has been proved that the conversion of Fe-Ni slag from wastes with high pollutant potentials into aggregates valuable for industry would express significant economic and environmental effects.
