The Effective Study of Black Cotton Soil Using Flyash and Geopolymer

Nearly 51.8 million hectares of land area in India are covered with Expansive soil (mainly Black Cotton soil). The property of these expansive soils, in general, is that they are very hard when in dry state, but they lose all of their strength when in wet state. In light of this property of expansive soils, these soils pose problems worldwide that serve as challenge to overcome for the Geotechnical engineers. One of the most important aspects for construction purposes is soil stabilization, which is used widely in foundation and road pavement constructions, this is because such a stabilization regime improves engineering properties of the soil. In the present study soil is considered namely Black cotton soil have been stabilized using geopolymers (Alkaline activators, sodium silicatesodium hydroxide in 21ratio). The alkaline solution, sodium silicatesodium hydroxide in 21 ratio was used in different concentrations. In this study deal with the obtaining the unconfined compressive strength values and California bearing ratio by fixing 25 % Flyash and % varying of Alkaline material (2 %, 4 %, 6 %, 8 % and 10 %).
