Strength Behaviour of Expansive Soil Treated with Rice Husk Ash-Phosphogypsum and Nylon Fibres
K. Venkatesh, Dr. D S V Prasad
Abstract: Expansive soils, popularly known as black cotton soils, are basically susceptible to detrimental volumetric changes, with changes in moisture. Various remedial measures like soil replacement, moisture control, pre-wetting, lime stabilization have been practiced with varying degrees of success. Stabilization using solid wastes is one of the emerging techniques to improve the engineering properties of expansive soils to make them suitable for use in construction. In this project, an attempt has been made to study the influence of two wastes, Rice Husk Ash (RHA) and Phospho Gypsum (PG) in different percentages, as stabilizing materials and also further enhancing the properties by mixing it with Nylon Fibres (NF). Parametric evaluation of different characteristics of treated expansive soil is done by conducting various tests in the laboratory. The results will be analyzed to assess the influence of the materials used.
