Abstract

Compacted clay liners are widely used for waste contaminant facilities because of their low cost, large leachate attenuation capacity and resistance to damage and puncture. Commonly used bentonite possess many limitations such as high swelling and shrinkage potential, sensitivity to waste fluid characteristics etc. The paper proposes the use of bentonite-sand mixture containing optimal clay content as liner material. It has been brought out, based on detailed geotechnical investigations, that a mixture containing only about 20 to 39% of bentonite is more suited than the clay alone and they possess.
