Effect of Ethanol on Compressibility Swelling and Permeability Characteristics of Bentonite–Sand Mixtures

Sand–bentonite mixtures are used to construct clay liner in engineered landfills. Clay-lined landfills when exposed to organic wastes produce leachate which affects the properties of the clay liner extensively, and it may become unreliable in being a permanent barrier to the wastes. This work is to investigate the behaviour of different bentonite–sand mixtures through one-dimensional consolidation using ethanol–water solution mixed in the ratio of 20:80 by volume, as the permeating fluid. The same series of experiments were performed with pure water also as the permeating liquid to get a good comparison of the change in properties. The percentage swell, swelling pressures and permeability were high in the mix with pure water solution. Compressibility was found to be high in the mix with ethanol–water solution. Good correlation exists between per cent swell and swelling pressure in the mix using ethanol–water solution and in the mix using water.
