摘要:Landfills must be highly engineered containment systems, designed to minimize the impact of soiledwaste on the environment and human health. The design of a liner, in the case of economically developing countries,will vary depending on a number of factors, including the potential of the landfill polluting the land and waterenvironments, the local hydrogeology and meteorology, and the availability of suitable materials and monetaryresources..In this paper, Flyash is used as a basic material, the properties of this material are altered by adding bentoniteto achieve the required properties of a competent material for landfill liners. Tests were conducted on fly ash with8,12,16, and 20% of bentonite clay by weight. The main factor affecting the quality of compacted clay liners/covers isits permeability which should not be greater than 1.0 × 10–9 m/sec. The appropriate Bentonite - Red soil mix and therange of compaction parameters was determined that would give the required hydraulic conductivity, strengthcharacteristics and minimum desiccation crack for their use as liner material.
