Abstract EN
Geotechnical applications based on soil resistivity measurement are becoming more popular in recent years.
In order to explore the potential application of the electrical resistivity method in stabilization/solidification of contaminated soils, two kinds of lead-contaminated soils stabilized with cement were prepared, and the electrical resistivity and unconfined compressive strength of specimens after curing for various periods were measured.
The test results show that a high lead content leads to a low value of electrical resistivity of cement-stabilized soils, and increasing cement content and curing time result in a significant increase in electrical resistivity.
The reduction in porosity and degree of saturation, as a result of the cement hydration process, leads to an increase in electrical resistivity.
The ratio of porosity-lead content/cement content-curing time, combining together the effect of lead content, cement content, curing time, and porosity on electrical resistivity of stabilized soils, can be used as a fundamental parameter to assess electrical resistivity of cement-stabilized lead-contaminated soils.
Archie’s law can be extended to apply to cement-stabilized lead-contaminated soils by using this ratio, replacing the porosity.
The new resistivity formula obtained in this paper is just empirical.
There is a power function correlation between unconfined compressive strength and electrical resistivity of lead-contaminated soils stabilized with cement.
Electrical resistivity measurement can be used as an economical and time-effective method to assess the quality of cement-stabilized lead-contaminated soils in practice.
