Abstract

Using cement as a binder to mix with contaminated soils is one of the widely used technologies for soil remediation. The experience formulas for the unconfined compressive strength prediction of cement stabilized/solidified heavy metal contaminated soils are studied. The strength data used for analysis are from unconfined compressive tests conducted in the laboratory. The heavy metal contaminated soils are prepared artificially by adding lead nitrate as a source of pollutant at four different lead contents of 1.0×102, 1.0×103, 1.0×104 and 3.0×104 mg/kg (dry soil weight basis) and three different cement contents 5%, 7.5% and 10%. The results of the unconfined compressive strength tests show that there is a linear relationship between the strength of cement treated lead contaminated soils at different curings, and a power function relationship between the cement content ratios and the ration of strength corresponding to the cement content. The experience formulas are further concluded which can predict the strengths at different curing times or with different cement content. These formulas are both appropriate for normal cemented soils and cement treated lead contaminated soils.
