Various in-situ techniques are used to treat heavy metal pollution including solidification/stabilization (S/S) with chemical binders which results in a solidified matrix and hence structurally stable soils. This study describes the impact of different amounts of various binders on shear strength behavior of contaminated loess. The contamination substance was chosen based on the fact that industrialization have increased the concentration of lead in natural environment; therefore, lead nitrate as soluble lead compound is used in this study. In order to solidify or stabilize the soil, different chemical binders are added to the contaminated soil. The binders used in this study include ordinary portland cement, pulverized fly ash, lime, rice husk ash, activated carbon and zeolite. Different amount of each binder will be used to evaluate their influence on shear strength of stabilized lead-contaminated loess. Shear behavior and shear strength properties will be obtained through conducting two series of triaxial compression and direct shear tests. The influence of each binders on shear strength characteristics of lead contaminated loess will be interpreted and discussed. In the end, suggestions for future research in this field are presented.
