Abstract
A field test was conducted to evaluate the use of GM and KMP to stabilize zinc (Zn) and chloride (Cl) contaminated soil at an abandoned industrial electroplating plant site in this study. The stabilized field soil was cured for 1, 3, 7, and 28 days and tested for dry density, dynamic cone penetration, soil pH and leachability. The results showed that the soil pH and leachable concentrations of Zn and Cl were well below their corresponding remediation goals. Furthermore, the KMP stabilized soil possesses superior performance in terms of higher dry density and strength in the early curing stage (7 days) and also lower dynamic cone penetrometer index and leachable Zn. While GM exhibited superior immobilization of Cl in the contaminated soil.
