Electrical Resistivity Of Sandy Soil With Water, Leachates And Seawater, Lopa Mudra Pandey

Theses: Doctorates and Masters

Liners are used in the engineered containment systems such as landfills for controlling the migration of contaminants. Although there are several techniques for detecting the leakages through the liners, use of the electrical resistivity method can assist in timely detection of contaminant migration in cost-effective manner. This method is based on the well-established fact that the electrical resistivity of soils and other geomaterials is much higher than the electrical resistivity of water, leachates or any liquid effluents which may permeate the landfill foundation material. Additionally, the geotechnical properties of a soil exhibit a close relationship with its electrical resistivity values …

Engineering Characteristics Of Compacted Sand-Bentonite Mixtures, Ali Faisal Ghazi

Theses: Doctorates and Masters

Sand-clay mixtures are commonly used as a liner/barrier material in various engineering applications, such as construction of hydraulic and waste containments. Permeability, compressibility and strength are important properties of sand-clay mixtures and are often required for the design of the liner/barrier of the containments.

In states like Western Australia, which is covered mostly by sandy soils, engineers face difficulties with economically sourcing clays for liner/barrier applications. Any reliable research finding that recommends an optimum clay content to be used with sandy soil can be of significant importance. Such findings for the local Perth sandy soil are rarely available in the …

Characterisation And Applications Of Iron Ore Tailings In Building And Construction Projects, Francis Atta Kuranchie

Theses: Doctorates and Masters

The mine tailings are generated as the wastes worldwide as a result of exploration, excavation, blasting, beneficiation and extraction of mineral ores. In Western Australia, due to the extensive mining activities and increasing low grade ores, there is generation of mine tailings in large quantities, which could lead to environmental and disposal problems. The common practice of handling the tailings are to store them in tailing dams or as stockpiles near mine sites. Limited quantities are sometimes used as backfills and other applications. The utilisation of tailings in building and construction projects, which may consume a large volume of wastes, …
