Evaluation of hydraulic conductivity and self-healing potential of punctured geosynthetic clay liner
An experimental study was conducted on the modified geosynthetic clay liner (GCL) specimen by replacing encapsulated Sodium Bentonite (Na-B) with different percentages of locally available black cotton soil (BCS). The specimens with punctured hole sizes of 4, 8, and 12 mm in diameter were tested for hydraulic conductivity and self-healing capacity assessed by improved triaxial apparatus. The flowing permeant was prepared with the heavy metals: iron, zinc, nickel, and total chromium based on the results of the chemical analysis of leachate collected from the municipal solid waste site (MSW). The experiment results were observed at 24, 48 and 72 hours. The results were analysed to identify the best specimen mix (Na-B and BCS) regarding the lowest hydraulic conductivity and highest self-healing potential. The results demonstrated that BCS can be utilized in modified GCL as an impermeable barrier for leachate percolation at the MSW dump site.
