Coupling MRI and XRCT to resolve structure–transport evolution during enzyme-induced calcite precipitation at the REV scale

This dataset supports the study of enzyme-induced calcite precipitation (EICP) in saturated sand columns under constant flow injection. The experiments investigate how CaCO3 precipitation alters pore structure, transport properties, and permeability at the representative elementary volume (REV) scale.
The dataset combines magnetic resonance imaging (MRI) and X-ray computed tomography (XRCT) with hydraulic measurements, enabling a direct linkage between pore-scale structural evolution and macroscopic transport behavior
