Field tests are conducted to evaluate a novel binder of SPC stabilized nickel (Ni) and zinc (Zn) contaminated clay at an abandoned electroplating industry site. Portland cement is selected as a control binder in the field tests for comparison purposes. The field stabilized soils are subjected to toxicity characteristic leaching procedure, pH value, dry density, dynamic cone penetrometer, portable falling weight deflectometers tests. The results show that field S/S using SPC and PC significantly reduce the leached Ni and Zn concentrations, and the leached concentrations are below the national quality standard of groundwater (GB/T 14848—2017) for class IV. The SPC exhibits superior immobilization of Ni and Zn in the contaminated soil. The pH values of contaminated soils increase with the addition of SPC or PC. However, the SPC stabilized soil has a lower value of pH (7.99) than that of PC (9.76) after 28d curing. It is also found that the bearing capacity and resilient modulus of the contaminated soils are significantly improved with SPC and PC solidification/stabilization, but the SPC stabilized soil has a lower bearing capacity and resilient modulus relative to the PC stabilized soil.
