Stabilization of Soil Using Flyash, Lime & Cement

Black cotton soil is considered to be problematic soil as it show major volume changes due to change in its moisture content. This volume change cause wide spread damages to building and roads necessitating stabilization of such soil prior to the construction. The present paper investigates the effectiveness of different stabilizing agent viz. lime, cement and fly ash with soil for improving its engineering properties. Soil samples were collected from district Morena, in state of Madhya Pradesh, in order to look in to the relative effectiveness, and arrive at appropriate proportion of stabilizing. (1) Lime, (2) Cement, (3) Fly ash alone and combination of (1) LimeCement, (2) CementFly ash, (3) Fly ash-Lime are used to stabilize the soil. Quantity of stabilizing agent varied from 2 % to 10 % of the soil weight and the performance is evaluated by observing variation in various engineering properties like Liquid Limit, Plastic Limit, and Plasticity Index.
