“…By using cement, heavy metals are converted to stable forms and are entrapped in the solid cementation matrix of the stabilized contaminant soil (Paria and Yuetl, 2006). Strength, permeability and leaching properties of S-S treated soils have been extensively studied by Yilmaz et al (2003), Antemir et al (2010), Kogbara and AlTabbaa (2011) and Du et al (2012) among others. Conner (1993) indicated that S-S with addition of cement-based binders is an established treatment technology for soils contaminated with inorganic compounds whereas relatively limited experience exists for its application to organic compounds, in particular petroleum hydrocarbons.…”

This paper presents an investigation into remediation of an anthracene-contaminated clay soil through experimental tests. Samples were prepared of uncontaminated and contaminated soil-cement with 20 and 30% cement. Unconfined compression tests (UCT) were conducted on the natural soil and soil contaminated with anthracene. In addition, similar tests were carried out on uncontaminated and contaminated soil-cement at different curing times. Leaching tests were also conducted on contaminated soil and

“…Through the infiltration test, the influence of pH and pore volume of flow (PVF) of the acid rain on the leaching of Ca and Pb, and hydraulic conductivity is evaluated. The effects of pH and presence of sulfate ions (SO 4 2− ) on the leaching characteristics of Ca in the soaking test are assessed.…”

“…Solidification/Stabilisation (S/S) is a treatment technique by which contaminated soils, sediments or waste are mixed with a binder and/or specific additives with the aim of decreasing the mobility of the toxic contaminants by increasing the pH and fully or partially binding the contaminants in the solid matrix (stabilisation), but also of improving the physical properties (strength, compressibility, permeability and durability) of the final treatment products (solidification) [1].…”

Abstract. The effect of replacing cement with rice husk ash (RHA) on compressive strength and leachability of Chromium stabilised sediments was investigated. Artificially contaminated sediment was prepared by spiking sediment with solution of Potassium dichromate (K2Cr2O7) to achieve an average of 1000 ppm target concentration. Cement was added at 10% and rice husk ash at 5%, 10%, 15% and 20% to the total dry weight of the mixture, which were then cured at room temperature (27 ± 3 o C) and humidity of 75 ± 5 % for 7, 14 and 28 days. The addition of RHA with cement to the spiked sediment increased the compressive strength (UCS) of solidified sample with increase in curing period. The reaction products and crystalline mineral phases were identified using X-ray diffraction (XRD) which shows the formation of various crystalline phases of the treated sediment after 28 days which explain the mechanisms responsible for immobilization of chromium under study. The UCS values of solidified samples at 7, 14 and 28 days exceeded the minimum landfill disposal limits of 0.34N/mm2 (340 kPa). It was observed that leaching of Cr (VI) was higher in acetic acid medium (TCLP) as compared to deionized water (DIW) medium. The leached chromium concentrations in the two different leachates (acetic acid, and deionized water) were all below the regulatory limits of 5 mg/l of U.S EPA. Results have indicated that the partial replacement of cement with RHA in the binder system has increased the strength and reduced leachability of chromium in the treated compared to untreated sediment samples.
