“…The stress-strain response of a clay soil in the face of a varying pore-fluid composition is mainly governed by the net result of two different opposing or non-opposing mechanisms, i.e. physico-chemical interactions and mechanical factors (Ratnaweera and Meegoda 2006;Dolinar and Trauner 2007;Zhan et al 2008;Olgun and Yıldız 2010;Liu et al 2015;Estabragh et al 2016bEstabragh et al , 2016cEstabragh et al , 2017. The physico-chemical effects are commonly interpreted by means of the diffuse double layer concept, which has been well-documented in the literature.…”

The AM is yet to be copyedited and formatted in journal house style but can still be read and referenced by quoting its unique reference number, the digital object identifier (DOI). Once the AM has been typeset, an 'uncorrected proof' PDF will replace the 'accepted manuscript' PDF. These formatted articles may still be corrected by the authors. During the Production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal relate to these versions also. Version of record The final edited article will be published in PDF and HTML and will contain all author corrections and is considered the version of record. Authors wishing to reference an article published Ahead of Print should quote its DOI. When an issue becomes available, queuing Ahead of Print articles will move to that issue's Table of Contents. When the article is published in a journal issue, the full reference should be cited in addition to the DOI.

“…It has also been shown that the bearing capacity of waste motor oil contaminated soil is drastically reduced and made unsustainable for supporting engineering structures or plant growth by increasing toxic content of the soil Mashalah [12]. Murat and Mustafa [13] reported that there is a variation in the hydrocarbon content of waste motor oil and the concentration of this hydrocarbon affect the extent to which waste motor oil influence the geotechnical properties of clay soil. According to a study carried out by Youdeowei [14] to investigate the effect of hydrocarbon on engineering characteristics of oil contaminated soils, it was observed that the change hydraulic conductivity of a particular soil can be associated with the changes in the soil and the soil fabrics when moulding pore fluid.…”

“…Deionised (DI) (MilliQ, 18 MX/cm resistivity) water (e * 80) was used as reference liquid throughout all tests Benson et al 2015). These compounds have been frequently used in compatibility studies of CCLs (Foreman and Daniel 1986;Bowders and Daniel 1987;Olgun and Yildiz 2010;Benson et al 2015) to represent different types of chemicals found in waste disposal units: neutral polar industrial solvents (methanol), waste oils and some industrial solvents (n-heptane), and recalcitrant hazardous chlorinated organic chemicals (TCE). Acetic acid was used to represent the organic acids fraction in waste landfill leachates (Ö man and Hynning 1993), and it is also used as leaching agent in the US EPA TCLP procedure (Halim et al 2004).…”

Red mud residue from alumina production has been proposed as an alternative liner material. The chemical and environmental compatibility of red mud upon exposure to representative organic (methanol, heptane, TCE, and acetic acid) and inorganic liquids (CaCl 2 and seawater) was studied. Chemical compatibility assays comprised Atterberg limits and sedimentation and hydraulic conductivity tests for red mud interacted with the chemical liquids, whereas the environmental compatibility was assessed through the leaching of metals from red mud as permeated with the liquids. Methanol greatly reduced the plasticity at concentrations C80 % by volume, but it did not increase the hydraulic conductivity of compacted red mud. High concentrations (C60 % v/v) of acetic acid reduced the plasticity and enhanced the sedimentation of red mud. Conversely, acetic acid concentrations B40 % caused dispersion, but damaged the hydraulic properties and structure of red mud. The percolation of a pH 2 acetic acid solution did not adversely affect the hydraulic performance of the red mud liner. Neither diluted heptane nor TCE affected the red mud. However, pure organics suppressed the plasticity and induced aggregation of red mud, suggesting a great detrimental effect on red mud liners. The red mud exhibited great resistance to attack by inorganic salt solutions. Some concerning leaching of metals (primarily Al and Cr) occurred as water, acetic acid, and CaCl 2 solutions percolated through red mud, but effluent metals concentration quickly dropped to permissible levels. In general, red mud exhibited a high resistance against chemical attack; nevertheless, exposure to low-dielectric-constant organic chemicals should be avoided.
