Lime stabilization of clayey landfill base liners: Consolidation behavior and hydraulic properties

Lime soil treatment is a chemical process in which lime (quicklime, hydrated or slurry) mixed with the place subgrade and reaction takes place. The reacts clay particles to create cementitious matrix. design of landfill base liners including layer as fluid barrier (i.e. water-resistant impervious layer) requires neat engineering approach considering, particular, consolidation behavior well hydraulic properties contained. For sake safe stable such baseliners under landfills, reduction settlement when subjected accumulated waste load superposed action) during operation accomplishment for ensuring waterproof those composite (comprised multiple different layers) not allow penetration contaminated water - produced result exothermic reactions occurring body landfills – by enabling enhanced isolation from natural ground importance. In light this, order address two most important concerns Consolidation Hydraulic Properties Clay) an at- tempt develop system that has greater bearing capacity resistance), hence, more robust against settlements, additionally, possessing improved being relatively greatly impermeable, series tests were performed laboratory at contents (lime/lime-clay mixture proportions weight: 0%, 10%, 20%) on specimens investigate stabilization improvement clayey baseliners. shown experimental program strength loading improves, further, exhibits less vertical deformation (settlement) owing increase content. Moreover, becomes highly impermeable displays substantially larger because increased mass proportion soil. findings demonstrate soils will benefit imperviousness (water tightness) compared standard multi-layered baseliner systems.
