Zmiany właściwości filtracyjnych mieszanki gruntowej ił-piasek na skutek zanieczyszczenia produktami ropopochodnymi w aspekcie mineralnych barier izolacyjnych

Abstract

Changes in the filtration properties of the sand and clay mixture as a result of contamination with petroleumproducts in the aspect of mineral insulation barriers.A b s t r a c t. The paper presents the results of research on the filtration coefficient of soil mixtures prepared from ice-dammed lake clays and aeolian sand. The determination of permeability coefficient made by the indirect and direct methods confirmed the influence of hydrocarbon contamination on changes in the permeability coefficient value. The implemented program of laboratory tests made it possible to propose a criterion that can be used to compare the filtration coefficient values determined by the applied research methods.
