Abstract: Several monotonic triaxial consolidated drained (CD) and consolidated undrained (CU) tests were conducted to investigate the effect of biogenic gas formation through microbial-induced denitrification on the mechanical ...

Abstract: This technical paper investigates the bearing performance of precast concrete piles embedded within calcareous sands with biogrouting at the pile toe. Loading tests of biogrout-improved and unimproved concrete model piles ...

Abstract: A field trial evaluated the potential of microbially induced calcite precipitation (MICP) through urea hydrolysis for ground stabilization. A bioaugmentation approach was employed in which locally enriched bacteria were ...

Abstract: A significant pressing issue in microbially induced calcium carbonate precipitation (MICP) is the characterization of the heterogeneous growth mechanics of calcium carbonate (CaCO3) crystals. This study aimed to visualize ...

Abstract: Excess nutrients in water such as nitrogen and phosphorus result in microbial growth and overfertilization of aquatic plants, increasing the rate of eutrophication in water bodies. This work investigated the application ...

Abstract: Biogrouting is a biological ground improvement method, in which microorganisms are used to induce carbonate precipitation in the subsurface in order to increase the strength and stiffness of granular soils. In this paper ...
