Diffusion in pulverized stone, a potential liner material
Construction of a waste disposal site requires an effective barrier that separates waste from a sub-base and minimizes the migration of contaminants from the site to an aquifer. Barrier layers most often used are natuarl clayey deposits or compacted clay liners and PEHD geomembranes. However, some regions, the Croatian karst for example, are mostly short of clay. For this reason, the use of pulverized stone - the by-product in the building-stone industry - as potential liner material was investigated. Considering diffusion is an important mechanism of contaminant transport through barriers, this paper describes the method and apparatus for determining diffusion coefficient of pulverized stone. Measured diffusion values were related to sample compaction and compared with physical properties of clay, geosyntetic clay liners and PEHD geomembranes. Other physical properties of pulverized stone such as filtration coefficient, density and particle size distribution were also presented. Finally, the suitability of pulverized stone for barrier construction was discussed based on the results obtained.
