Iły poznańskie jako izolacyjne bariery geologiczne składowisk odpadów komunalnych

Projects for the storage of municipal waste involve systems of successive safety barriers consisting at least of a geomembrane and a natural mineral layer. “Poznań Clay” are among materials which can be used as a mineral layer. In this paper mineral layers standards from different countries are described. Studies of the important properties of “Poznań Clay” such as hydraulic conductivity, mineral composition, and void ratio are presented. Samples with undisturbed and disturbed structure were examined. Differences between properties of these samples are negligible.
