Abstract
Microorganisms are used in microbial geo-technology to amend the stability and bearing capacity of soil. In this research, bio-cementation process is induced in sand by using the microbial solution, calcium hydroxide and urea to enhance the physical features of the soil. Stabilization of buildings built on sandy soils using cementitious materials is an effective technique utilized all over the world to boost bearing capacity. The microbial solution was prepared using different natural elements and the sandy soil is cured in the solution for different intervals. The effects of mechanical properties of the sandy soil were observed. The parameters like California bearing ratio, direct shear strength and water permeability test were tested. Considerable improvement was observed in the various properties of sandy soil.
