Expansive soil. Alkali activated fly ash. Unconfined compressive strength (UCS) . Rheological properties

In India nearly 51.8 million hectares of land are covered with expansive soil. Because of cohesiveness the property of expansive soil is hard in dry state and soft in wet state. Stabilization of soil is one of the most important aspects in construction industry, which is widely used in foundation and road pavement construction. Materials formed using reactions between silica and alumina and alkali cations such as sodium or potassium are very similar, at a molecular level, with natural rocks. At higher levels the alkali activated materials shows improved mechanical character than cement. The activated fly ash at different alkali concentrations and potassium hydroxide and fly ash ratio also tested. The different geotechnical properties like Atterberg’s limits, compaction and strength behavior of stabilized soil were tested. It is observed that with the addition of alkali activated fly ash there is a considerable improvement in geotechnical properties expansive soils.
