Description

Mercury intrusion porosimetry (MIP) and X-ray micro-computed tomography (X-CT) techniques were used to characterize the pore structure of strontium-source biocemented calcareous sand and quartz sand. Considering the impact of different grouting cycles and depths on treatment, MIP results can be used to characterize pore parameters, including total pore volume, porosity, and pore size distribution (PSD). Additionally, 3D pore models were reconstructed using X-ray CT images to extract pore parameters. Additionally, the Finite Volume Method (FVM) was used for direct seepage simulation at the pore scale to investigate the relationship between the pore characteristics and permeability. The raw data of this study were upload here.
