This work initiated the development of operating envelopes for stabilised/solidified contaminated soils. The operating envelopes define the range of operating variables for acceptable performance of the treated soils. The study employed a soil spiked with 3,000 mg/kg each of Cd, Cu, Pb, Ni and Zn, and 10,000 mg/kg of diesel. The binders used for treatment involved Portland cement (CEMI), pulverised fuel ash (PFA), ground granulated blast furnace slag (GGBS) and hydrated lime (hlime). The… Expand

Process envelopes for stabilisation/solidification of contaminated soil using lime–slag blend
TLDR
The results show that greater than 20% dosage would be required to achieve a balance of acceptable mechanical and leaching properties, and overall, the process envelopes for different performance criteria depend on the end-use of the treated material. Expand
