“…Contaminants get adsorbed onto the clay particles leading to marked changes in the geotechnical and chemical characteristics of the soils. Past work (Foreman and Daniel 1986;Gnanapragasam et al 1995;Kamon et al 1996;Khan and Pise 1994;Kirov 1989;Kumapley and Ishola 1985;Mesri and Olson 1970;Nayak et al 2007;Roque and Didier 2006;Sivapullaiah and Savitha 1997;Soule and Burns 2001;Sridharan et al 1981;Sridharan and Venkatappa Rao 1979;Sunil et al 2006Sunil et al , 2008Uppot and Stephenson 1989) has shown that the index and engineering properties of contaminated soil tend to change due to chemical reactions between the soil mineral particles and the contaminant.…”

To study the impact of salt water intrusion on two types of soils from west coast region of India were investigated in the laboratory. The key characteristics evaluated included Atterberg limits, compaction characteristics, hydraulic conductivity and chemical characteristics of selected soils. The sea at this coast receives effluent from different points and hence the characteristics change with time and locality. Therefore, to maintain uniform composition, 0.5 N sodium chloride solution (NaCl) was prepared in the laboratory and batch tests were used to determine the immediate effect on soils. Soil specimens were prepared by mixing the soils with 0.5 N NaCl in the increments of 0, 5, 10 and 20% by weight to vary the degree of contamination. Experimental results of soils mixed with 0.5 N NaCl showed that the maximum dry density increases and the optimum moisture content (OMC) decreases with increasing sodium chloride concentration. The study also revealed that the hydraulic conductivity of the soils tested increases with increase in sodium chloride concentration. The Atterberg limits of contaminated specimens show a remarkable change when compared with uncontaminated specimens.

“…Due to the low pH, acid rain has caused degradation of performance and reduction of life cycle of construction facilities such as concrete bridge piers and concrete road pavements [6]. Upon exposing to the acid rain, performance of CHMS can be weakened due to the drop in pH, which will lead to dissolution and decomposition of cement hydration products such as Portlandite (Ca(OH) 2 ) and calcium silicate hydrate (CSH) in the soil matrices [8]. Coupled with the dissolution of cement hydration products, calcium (Ca) will be released and leached from CHMS, causing reduction in strength and degradation of other mechanical properties [8].…”

“…Kamon et al (1996) also revealed same limited improving effect of additional immobilizing agent content after curing. The similar improving effect indicates that the extent of hydration reactions of two cases is similar, which is due to the insufficient water amount in the curing period.…”

Excavated soils and rocks generated from construction works sometimes contain heavy metals derived from nature. Without proper treatment, these soils will generate hazardous leachate and cause environmental contamination. Sorption layer method is a newly developed technology which has a potential to be an economical countermeasure. It utilizes a permeable soil layer with sorption capacity lying beneath piled soil and rock in embankments to retain the chemicals of concern dissolved in the leachate, thus making the effluent meeting the environmental standard. In this study, the performance of sorption layer by mixing decomposed granite soil with Ca/Mg composite immobilizing agent is discussed. The mechanical, hydraulic and sorption performances of soil-immobilizing agent mixture affected by different mixing ratio and curing period is evaluated. Experimental results showed that curing increase the unconfined compressive strength of the mixture. Higher immobilizing agent content exhibited higher sorption capacity.
