Soil Stabilization with Nanomaterials and Extraction of Nanosilica: A Review

The ability varied in the volume changes under moisture content in soft clays. The soil transformed into weak in the supporting of the structure leads to fail in various construction and geotechnical engineering failures. These type soils under these situations needed to stabilize with additives before making a substantial basement, embankment, and excellent foundations for any structures. This chapter approaches with analysis or reviewof some earlierworks of literature done to develop the geotechnical properties of very soft clay by using nanomaterials such as terrasil and nanosilica. The properties of nanomaterials are excellent bonding with soils. The preparation and availability of nanomaterials are also needed to stabilize weak soils. The preparation of nanosilica from agricultural wastes using acid mixtures is mainly concentrated, and the microanalysis for stabilization with nanomaterials, and preparation of nanosilica by XRD, EDS, and FT-IR is done.
