Comparison of three Tunisian clayey soils for containing acid waste

Hamdi, Noureddine / Marzouki, Aidi / Srasra, Ezzeddine

Abstract Three natural soils from Tunisia we are studied to assess their suitability for use as a liner for a acid waste disposal site at Gabes. The dominant minerals were palygorskite (soil 1), smectite (soil 2) and illite (soil 3). X-ray diffraction (XRD), grain size, Atterberg limits, permeability (with water and waste solution), consolidation and shear strength tests were undertaken. Soil 2 had the highest Atterberg limits and lowest shear strength, while the permeability of soil 3 increased significantly over time when tested in a simulated leachate. It was concluded that soil 1 from Sebkhat El Maleh-El Mkhachrma was the most suitable.
