“…The liquid limit is increased with diesel addition, and this behavior is explained by two reasons. The first is that diesel gives an additional cohesion to soil which needs more water to change the state, and the second is that diesel does not decrease the diffuse double layer of the clays, which result similar with other authors [12,22,24]. On the other hand, the increase in liquid limit at 50 ± 5 °C is smaller than at 110 ± 5 °C because this temperature has higher evaporation rate; therefore, temperature is a key factor to calculate the magnitude of changes in soil properties.…”

“…This behavior is explained because the clay particles structure is destroyed by the diesel adhered to solid soil particles that have reorientation of water molecules and modify the adsorbed layers, which has relation with a higher cationexchange capacity of the soil. This behavior was reported by different authors [5,12,16,22], and they explain that water molecules interact with clay minerals to give a cohesive behavior and resist load; however, the diesel is not able to do it and reduces strength.…”

“…For diesel content of 1%, it is 30.0%, and for diesel content of 6% is 30.9% at 50 ± 5 °C, which represents an experimental variation of 3.00%. The increase in the plastic limits is explained because diesel adhered to the soil particles, which needs more water to change the consistency [12,22,24]. In addition, molding the ball and rolling it between the palms on the hands was complex and needed much time to get the plastic limit with the increase in diesel content because expelling diesel from the soil structure requires much time, and the soil with diesel tends to become harder near the limit.…”

Diesel contamination in the soil may occur in different ways, and its interaction in the soil is uncertain and may have negative impacts. This paper presents the interaction between clay soil with moisture content of 30% and diesel content of 1%, 3% and 6% of dry mass. The soil is taken from Colombia to know the effect of diesel on the index properties (moisture content, specific gravity of solids, Atterberg limits), cation-exchange capacity, mineralogy composition and unconfined compression strength; moreover, the samples are tested at different temperatures considering if it is known the presence of diesel or not in the soil because the presence of diesel increases organic components, then if there is known the presence the temperature is 50 ± 5 °C but 110 ± 5 °C. The diffractograms showed that diesel did not affect the mineralogical composition in the exposure period of 7 days, but in real cases the hydrocarbon may be for prolonged periods, months or even years. Independent of the test temperature, there was an increase in moisture content and decrease in specific gravity of solids as diesel content increased. The Atterberg limits had an uncertain behavior by the presence of diesel and change in the test temperature. The cation-exchange capacity was increased by the presence of diesel independent of the test temperature. The parameters of unconfined compression strength decreased as diesel content increased. The research concludes that diesel effects over geotechnical parameters of the soil generates negative impact, and projects that have soils with diesel need special attention, so it is important to keep doing research where diesel has more time of exposition in the soil.

“…The test results are largely consistent with the majority of reported results found in the more recent literature sources (e.g. Ratnaweera and Meegoda 2006;Khamehchiyan et al 2007;Estabragh et al 2016bEstabragh et al , 2016cNasehi et al 2016;Estabragh et al 2017). Any inconsistency can be attributed to the differences between the type of soil, the type of contaminant agent, and the range of tested degrees of contamination.…”

“…He determined that by increasing the percentage of pollution content from zero to 1%, the coefficient of permeability decrease at first and after that increase from 1% to 6% and finally decrease from 6 to 20%. Nashi et al (2016) investigated the effect of gas oil pollution on the geotechnical properties of three different soil types, SP, CL and ML [20].The results of the experiments on the CL and ML samples demonstrated that by increasing the percentage of contamination, the liquid limit and plastic limit increase and the plasticity index value decreases. The standard proctor compaction test on all three soil types indicated that by increasing the percentage of contamination the maximum dry density decrease in all three samples.…”

This research studies the behavior of circular foundations rested on the soils contaminated with gas oil and kerosene oil under cyclic loading. The final goal of this study was to determine the influence level of the foundation of the reservoirs rested on oil-contaminated sand due to their filling and discharging. The contaminated sand layers were mixed with different percentages of contamination from 2 to 6 of kerosene oil and gasoline. The effect of the contamination percentage, the value of the applied load, as well as the depth and type of contamination is investigated in this study. To validate the numerical studies performed by finite element software, small-scale laboratory tests is carried out.The results showed that the pollutants could affect the amount of final settlement and the number of loading cycles to reach this value. Increasing depth, the number of load cycles and the contamination content increased the final settlement and the 2 number of loading cycles to reach that level increases. Numerical results showed a good compatibility in the load-settlement charts with the experimental results.
