... of civil engineering infrastructure. Traditional calcium-based stabilisers raise environmental concerns and may trigger secondary swelling. This study explores a novel approach to soil stabilisation by directly activating aluminosilicates in a synthetic soil simulating the mineralogical composition...

...P. V. Sivapullaiah; Manju The paper brings out the use of lime to control the high volume change induced by caustic soda solution in a non-swelling soil. Soil–alkali interactions, which produce mineralogical changes such as the formation of zeolite, can cause swelling in non-swelling kaolinite...

... the swelling of expansive soil is investigated. A new technique to further enhance the efficiency of the lime columns technique in reducing soil swelling is also investigated, namely reinforced lime columns. The new technique involves reinforcing the lime columns using reinforcement bars attached...
