Abstract
Expansive soils such as black cotton soil are very susceptible to detrimental volume changes, with changes in moisture. This behavior of soil is attributed to the presence of mineral Montmorillonite which has expanding lattice; Expansive soils because of their specific physical & chemical make are subjected to volume changes. In many countries including India, these soils are so extensive that alteration of highway route to avoid the material is virtually impossible. Various remedial measures like soil replacement, prewetting, moisture control, lime stabilization etc have been practiced with varied degree of success. Extensive research is going on to find the solutions to black cotton soils. Recent investigations on chemical stabilization revealed that strong electrolytes like potassium chloride, Ferric chloride can be used in place of conventionally used lime due to their ready dissolvability in water and supply of adequate cations for ready cation exchange. In the present work experimentation is carried out to investigate efficacy of ferric chloride and fly ash in improving the properties of black cotton soil.
