Abstract Microstructural (fabric, forces and composition) changes due to hydrocarbon contamination in a clayey soil (glacial till) were studied using scanning electron microscopy (microfabric analysis), atomic force (force measurement) sedimentation bench test (particle size measurements). Non-polluted polluted glacial till from NE Poland (in the area of fuel terminal) used for study. Electrostatic repulsive samples much lower than non-polluted samples. In comparison with samples, exhibited...
The paper presents a study on the shrinkage properties of three clay soils from Poland. Shrinkage limit, volumetric and relative were determined, tested according to PN-88/B-04481 (1988) BS1377: Part 2 (1990) correlated with index soils. limit was also calculated Krabbe's (1958) equation. results showed that values obtained by BS method are lower than those using PN method, but equation differ significantly. While no strong correlation found between soil parameters, linear relationships...
The revision of classification methodologies for determination soil expansivity revealed that parameters most frequently used this purpose are: the liquid limit, plasticity index and swelling which also predominate in older systems expansive assessment, regarded as classical. Seventy-nine samples, including Neogene clays glaciall tills from Central Poland, with a wide range were examined comparative analysis use eight empirical methods. study are mostly highly very expansive, while glacial...
Petroleum products influence the engineering behaviour of soil. Neogene clays and glacial tills from Central Poland were tested under laboratory conditions to evaluate changes selected physical mechanical parameters: particle size distribution, density, swelling, shear strength permeability. Four petroleum used in experiments: diesel fuel, kerosene, jet fuel mineral engine oil. The study revealed that even for lowest degree contamination values properties soils changed significantly. Greater...
This paper presents the characteristics of expansivity and quantitative prediction heave clay soils from Poland based on suction testing. 11 Neogene clays 6 glacial tills, differing in genesis plasticity, were analyzed to identify expansive potential using eight empirical methods. The laboratory studies included measurements soil-water characteristic curves soil index properties . Data water content, volume served determine compression C h suction-water content Dh/Dw examined. values these...
The paper presents the results of free swell measurements Neogene clays and model clay mixtures composed Wyoming bentonite Sedlec kaolinite. Modified index (MFSI) as well ratio (FSR) were determined analyzed with respect to pore fluid chemistry, mineral composition content. FSR, defined equilibrium sediment volume 10-g oven dried soil in 0.0025% NaCl solution that kerosene, has proved provide only a rough prediction mineralogy natural soils.
The objectives of this paper are to provide a regional description the shrinkage parameters Neogene clays and glacial tills from central Poland; present effects hydrocarbon contamination on behaviour soils. Forty samples containing 19 90% clay-size particles were tested. comparison three methods applied has indicated that limit values obtained by BS 1377-2 method greater margin safety when used in classification expansive soils yield best match analysis variability relation other soil index...
This paper deals with the prediction of free heave in expansive soils from central Poland.Thirty-nine soil samples differing plasticity were selected for a comparative analysis.The types examined -Neogene clays, alluvial soils, and glacial tills -differ CLOD index (C w ) values, which range 0.027 to 0.019, values undisturbed being higher than those remoulded ones.The variability C correlates best sand-to-clay ratio.Studies contaminated diesel oil (ON) have revealed that decreases growing ON...
A b s t r a c t.The paper presents the results of testing flood facies sediments -muds.The term "muds" refers to genetic type deposits, regardless their variability in particle size composition and organic matter content.Due poor geological engineering properties, such as, high lithological variability, low degree diagenesis, as well moisture content content, muds are classified weak soils river valleys areas complicated ground conditions.The lithological, physical chemical properties from...
