In-Situ Fluid Injections To Achieve Bio-Stimulated Calcite Precipitation In Expansive Soils, Anish Pathak
Boise State University Theses and Dissertations
Expansive soils undergo vast changes in volume when subject to change in water contents and cause damages to infrastructures across the world. Traditional methods of tackling the problem of expansive soils using cement or lime are environmentally unfriendly and expensive. Microbial Induced Calcite Precipitation (MICP) is a new method which uses bacteria in the soil to precipitate CaCO3 (calcite) and improve the engineering properties of soils. Various laboratory studies have shown that this method can be applied successfully to treat expansive soils, but the field application of the method have barely been studied.
To study the applicability of MICP in …
