GEOTECHNICAL CHARACTERISTICS OF INDUSTRIAL WASTE SLAG AND SLUDGE FROM SMEDEREVO STEEL MILL, SERBIA

摘要

In 2011, steel mill in Smederevo has started with the construction of the first certified plant for the industrial waste management in the Republic of Serbia. The most important facility of this plant is the industrial waste landfill with independent cells: bigger for non-hazardous waste disposal and smaller for hazardous waste disposal. Since this is the earthfill structure with a planned height of 50 m, one of the main geotechnical problems, which is being analysed in these cases, is landfill slope stability. Geotechnical parameters, especially shear strength parameters (internal friction angle - phi' and cohesion c') as well as general physical parameters (unit weights, moisture content, particle size distribution, permeability) are used in these analysis. Their values, obtained by laboratory geomechanical tests on different samples of slag and sludge, are presented in this paper.
