Soil Stabilization Using Fly Ash and Silica Fumes

Abstract

The use of waste resources as building materials due to their applications causes serious concern for engineers in various fields. In light of this, studies on the usage of waste products will assist in resolving several environmental issues and lead to innovative, practical engineering discoveries. Clayey soils or expansive soils can pose difficulties for civil engineering projects as they do not have enough strength to withstand the loads imposed on them during construction or during the structure's operational life. This paper reviews different studies done on the effects of silica fume and fly ash on clayey soils. The researches reveal that silica fume and fly ash perform well to enhance the properties of clayey soils.
