Consolidation behaviour of the neutralisation spent pickle liquor (NSPL) sludge from steel works

The disposal of industrial waste sludge at a landfill has become a global problem especially when dealing with high moisture content material. Neutralisation Spent Pickle Liquor (NSPL) sludge waste generated in steel industry has been categorized as one of the slurry wastes in geotechnical engineeri...
