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

“…Although cement-based S/S is a widely applied and well-established technique for the immobilization of organic hazardous constituents (Karamalidis and Voudrias, 2007) but S/S technology has run into difficulties when trying to solidify organic waste (Vipulanandan, 1995 andOuki andHills, 2002). Some researchers such as Botta et al (2004) used organic clays for S/S of 2-choroaniline. Most of the current research efforts in this area focus on organophilic clays which are formed by exchanging the naturally occurring cations, such as Na + , K + , Ca 2+ and Mg 2+ .…”

Stabilization and solidification a clay soil contaminated with MTBE Abstract:This paper presents an investigation into stabilization and solidification of a clay soil contaminated with MTBE (Methyl Butyl Ether) using two different agents (cement and mixture of bentonite and cement) through a program of laboratory experiments. The samples were prepared in two stages. In the first stage they were prepared with 20 and 30% cement but in the second stage they were prepared with 20 and 30% mixtures of bentonite and cement (with ratios of bentonite to cement equal to 1:1 and 3:1).Unconfined compression tests (UCT) and leaching tests using GC (Gas Chromatography) apparatus were conducted on the samples that were prepared in the above two stages at different curing times. The results show that by using cement, the strength of the soil is increased. The results of the leaching tests on contaminated soil show a major reduction in the concentration of MTBE. Adding cement to contaminated soil causes reduction in concentration of MTBE but by increasing the curing time the concentration of MTBE is increased. It is also indicted that using combination of bentonite and cement leads to reduction in MTBE concentration and the amount of reduction is decreased by increasing the curing time. The bentonite-cement ratio of 3:1 is more effective than 1:1 in reducing the concentration of MTBE.

“…SEM is now widely used for explanation of different types of soil behaviour (Collins and McGown 1974). Some researchers such as Tremblay et al (2002), Botta et al (2004), Cai et al (2006) and Yazdandoust and Yasrobi (2010) used the SEM analysis for observing the microstructure of soil samples under different conditions (contaminated, mixed with cement, etc) and for explaining their observed behaviours.…”
