Abstract
Stabilization is one of the soil modification technique is for modifying the properties of a soil to improve its engineering performance. Dramatically increased construction activities demands more area, and final outcome was scarcity of land with proper strength characteristics. In all the geotechnical works, it is impossible to locate a construction site that with proper design requirements. Mostly, the sites with unsuitable soil are modifying by the various ground modification methods to change its engineering properties to meet the design necessities. Stabilization is being used for a variety of geotechnical works and its main objective is to increase the soil stability of to reduce the construction cost by making best use of locally available materials. This study was to perform a feasibility study concerning the use of Microbial Induced Calcite Precipitation to strengthen the problematic soil by Bio-cementation. As the size of geotechnical development, for example, land recovery is generally huge; a microbial treatment could be one of the most practical strategies. The main considerations that influence the utilizations of microorganisms to geotechnical building incorporate the screening and recognizable proof of reasonable microorganisms for various applications and various conditions, the advancement of microbial action in situ, bio safety of the application, cost adequacy, and soundness of soil properties after bio adjustment. Among all the variables, cost viability is the most significant factor for huge scope application. The microbial actuated cementation technique is the utilization of microorganisms with supplements as a vitality source. Microscopic organisms are round, bar like, or winding formed without layers shut core with a straightforward cell structure. Sizes differ somewhere in the range of 0.5 and 3 mm. Cell development and propagation of microorganisms need carbon to frame the particle in the cells and vitality to support life. Microorganisms live in oxygen consuming and anaerobic conditions, and are heterotrophic. Vigorous microorganisms live in a domain with free or broke down oxygen, as opposed to anaerobic microbes. The semi-penetrable cell film controls the vehicle of synthetic substances and electrical charges in and out. Precipitation of carbon dioxide on the microscopic organisms surface changes from mud to rock.
