“…Due to its fixed and non-breakable structure, lead present possible risks because of its bioavailability (Ragnvaldsson, Berglind, Tysklind, & Leffler, 2007). Most soils especially fine-grained soils easily absorb lead onto themselves (Ojuri, Akinwumi, & Oluwatuyi, 2017), this attribute heightens with an increase in the soil's organic content, CEC (cation exchange capacity) and pH (Zhang et al, 2015). On the other hand, polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds that consist of two or more fused benzene ring structures in various arrangements (Environment Agency, 2003).…”

This article presents an investigation on the influence of Ordinary Portland Cement (OPC) as a binder in the stabilization treatment of lateritic soil contaminated with lead or naphthalene. To evaluate the performance of the binder, the contaminated soils were tested for mechanical strength and environmental performance before and after the stabilization treatment. Results showed that the strength as inferred from the unconfined compressive strength (UCS) and cohesion values increased with the addition of the binder. Cement stabilization of the lead contaminated samples also prompted a reduction in the release of lead below the admissible limit during the leaching test. Cement stabilization of the naphthalene contaminated samples, on the other hand, could not contain the release of naphthalene below the regulatory level during the leaching test. The batch equilibrium adsorption test (BEAT) showed that cement stabilization increased the adsorption capacity of the soil for the contaminants.

“…Harbottle et al reported in 2007 an estimated cost of S/S remediation of 28 £ ton À1 (about 20 V ton À1 ) of soil for the in situ remediation of soils contaminated with BTEX and TPHs. More recently, Zhang et al (2015) screened S/S treatments suitable for lead-contaminated soil. Authors showed a cost of amendments of 22.3 $ ton À1 (about 20 V ton À1 ) per ton of soil when the Pb concentration in soil ranged from 2000 to Fujiwara et al (2012) 3000 mg kg À1 .…”

“…Pb is hazardous to the environment and human health and degrades the mechanical properties of soils [2]. Bioremediation, washing restoration, and phytoremediation are promising useful remediation methods for Pb-contaminated soils, while solidification/stabilization has been widely used to immobilize Pb-contaminated soil due to its relatively low cost and demonstrated effectiveness over many years [3]. Ordinary Portland cement (OPC) is a binder that has been used in solidified/stabilized Pbcontaminated soils because of its relative convenience and economic advantages [4].…”

Ordinary Portland cement (OPC) is widely used in the solidification/stabilization of Pb-contaminated soils. However, many studies have suggested that the high content of Pb would degrade the mechanical properties of OPC-solidified/stabilized soils. is paper presents a new binder, geopolymer fine aggregate (GFA), composed of ground granulated blast furnace slag, fly ash, CaO, and Na 2 SiO 3 . For comparison, OPC was used as a conventional binder. Mechanical properties and leaching characteristics are typically used to evaluate the effects of binders on solidified/stabilized soils. Nevertheless, limited information on the mechanical properties and leaching characteristics of the GFA-solidified/stabilized soils is available. is study thus investigated the mechanical properties and leaching characteristics of geopolymer-solidified/stabilized Pb-contaminated soil. Unconfined compressive strength test, permeability test, synthetic precipitation leaching procedure, simplified bioaccessibility extraction, phytoavailability extraction (with diethylene-triamine penta-acetic acid), sequential extraction procedure, mercury intrusion porosimetry, and scanning electron microscopy (SEM) were performed on OPC-and GFA-solidified/stabilized soil. e results showed that the GFA presented a better effect on the mechanical properties and leachability of the solidified/stabilized soils than the OPC-solidified/stabilized soils. e GFA-solidified/stabilized soil displayed considerably lower leachability, bioaccessibility, and phytoavailability of Pb and higher mechanical properties and chemical stability than the OPC counterpart. is study demonstrated that GFA had a better effect than OPC on the solidification/stabilization of Pb-contaminated soils.
