Experimental study on permeability and strength characteristics of MICP-treated calcareous sand

Biogeotechnics, 2023
Calcareous sand is the main fill material for island reclamation projects, but untreated calcareous sand might not be used as a reclamation fill due to its poor mechanical properties.
