“…Kabir and Taha [16] specified that soils used in waste containment system as isolation barriers are expected to sustain certain amount of static load exerted by the overlying waste materials. Daniel and Wu [7] mentioned that soil used as barrier material should have minimum unconfined compressive strength of 200 kN/m …”

Abstract-Some residual clay soils from southwestern Nigeria have been investigated with a view to elucidating their geotechnical properties and determine the possible variations in these properties in relation to the sampling distance. Eight bulk residual soil samples from two test pits separated 30m apart at intervals of 0.5m up to a depth of 2.0m were analyzed in the laboratory to determine specific gravity, grain size distribution, consistency limits, linear shrinkage, unconfined compressive strength and compaction characteristics. The data generated were subsequently subjected to statistical analysis. The investigations revealed that the soils are generally well graded, inorganic, with medium to high plasticity and hence compressibility and are of the same geologic origin. Statistical T-test showed no significant difference exists between the soils in terms of specific gravity, liquid limit, plastic limit, plasticity index, linear shrinkage, % clay size fraction, amount of fines, unconfined compressive strength and optimum moisture content. However the maximum dry density of the soils from both pits differed significantly. Although most of the parameters examined are not as varied and showed insignificant difference, the equations generated provide an option in the estimation of properties considering the close sampling distance.

“…However, literatures depict that soil with following index properties: percentage of clay (fraction smaller than 0.002 mm)≥20 to 25 %, percentage of fines (fraction smaller than 0.075 mm)≥50 %, plasticity index (PI)≥12 to 15 % and activity≥0.3 may be considered as landfill liner materials in waste containment structures [26], [29], [30]. Based on the above criteria, it is observed that the studied soil complied the standards and requirements for using as landfill liner material.…”

“…The shear strength of the remolded soil compacted at maximum dry density and optimum water content was found to vary with depth below ground surface as exhibited in Table III. Daniel and Wu [29] reported that the soil used as liner should have minimum shear strength of 200 kN/m 2 . Test results (Table III) show that the soil possesses higher shear strength than the recommended minimum shear strength for any depth below surface.…”

Abstract-Use of compacted silty clay soil collected from the Gangetic river sediment near Kolkata, West Bengal, India has been experimentally explored in the laboratory as a low cost landfill liner material for retarding the migration of phenolic compounds releasing from a coke oven wastewater outfall site in Durgapur, West Bengal, India. The phenol concentration in the wastewater was found in the range of 4.0-12.0 mg/L in different times of a calendar year. Batch adsorption results reveal that the maximum phenol removal efficiency of 95% was achieved at an initial phenol concentration of 4 mg/L for the soil dose of 20 g/L, solution pH of 6.0 and after a reaction time of 24 h. Index properties, swelling potential, compaction characteristics and permeability of the soil indicate that it is low compressible, moderately expansive and low permeable (1.90×10 -8 cm/s) and having reasonably good phenol attenuation capacity (472.5 mg/g). These favorable findings suggest that the compacted clay soil can be potentially utilized as primary landfill liner material for containment of phenolic waste generated from coke oven wastewater.

“…[8] suggested that the unconfined compressive strength of the compacted clay liner should be greater than 200 kPa. [8] suggest that an acceptable limiting value of volumetric strain to prevent desiccation for the soil should be less than or equal to 4%. …”

The goal of this study is to investigate the possibility of using the Irbid city clayey soil as compacted clay liner. The geotechnical properties and the permeability characteristics of compacted clayey soil sample obtained from the eastern part of Irbid city were determined to evaluate their suitability as compacted clay liner. Falling head permeability test, unconfined compressive strength and volumetric shrinkage test were conducted on soil samples that were compacted at about 0% and 3% wet of its optimum water content. The leakage rates expected through clay-only and composite geomembrane-clay liners were determined. It could be concluded based on the results of the geotechnical tests and leachate rate calculations that Irbid clay is appropriate to be used as compacted landfill liner material.
