Stabilization of Contaminated Soils

The elution behaviour of acid and alkaline soils, contaminated with diesel oil, PER and mercury salt, of different grading curves (sandy loam to loam-free fine gravel), was examined both before and after stabilization with cement. After cement stabilization, all heavily contaminated soils (eluate class Ill) yielded an eluate that corresponded to eluate class I. The stabilized soils had a permeability of iO rn/s to 10b0 rn/s. Any deterioration of the k-value required for applications within that range does not appear to be necessary. Soils with a component of adequate coherence are, however, favourable.
