This paper presents results of field and laboratory permeability tests aimed at evaluating the performance of mineral barriers for the containment of organic liquids (Non Aqueous Phase Liquids, NAPL). Experimental landfills were constructed following optimal ranges of variation of soil index properties proposed previously and the performance of the land...
View ArticleThe study evaluated, through a series of permeability and diffusion tests, the hydraulic and the attenuation behavior of a compacted clayey soil, with and without the addition of Portland cement (0 to 2%). To evaluate the diffusive response, the specimens were subjected to a vertical static load (100 to 500 kPa), simulating the action of a waste mass, a...
View ArticleMunicipal solid waste (MSW) settlement can be understood as volume reduction of the waste mass disposed in a landfill. Such phenomenon is mainly the result of organic matter degradation. Settlement can also be generated by MSW distortions, particle rearrengements, and other factors. These factors can be accurately analyzed if studied in an MSW experimen...
View ArticleElectrical resistivity tests have long been used in geo-environmental site characterization because they provide qualitative data to identify the presence of contaminants in soil. The measurement of soil electrical resistivity is affected by many intervening factors, which are usually studied separately in the laboratory and are important to ensure the ...
