Abstract: Microbial-induced carbonate precipitation (MICP) methods have been developed in recent years for soil improvement to simultaneously increase the shear strength and reduce the permeability of soil or aggregate. However, ...

Abstract: Microbially induced carbonate precipitation (MICP) utilizing a urease active bioslurry is an ecofriendly method that can improve soil strength. However, the micromechanisms, such as ion diffusion, production rate of CaCO3, ...

Abstract: Rheological characteristics are one of most important properties needed to be considered in the design and construction for the long-term stability and serviceability of underground structures in the rock mass. To date, ...

Abstract: To increase the efficiency of biogrouting for coarse sand or gravel, a premixed injection method with or without pH adjustment was developed and adopted for biogrouting of aggregates with grain sizes ranging from 0.75 to ...
