Slurry infiltration characteristics of coral reef limestone based on infiltration column tests and CT scanning

• Increased slurry concentrations and pressures generally improve filter cake formation, but excessive pressure can compromise its integrity. • Dijkstra's algorithm applied to pore network models identified primary seepage pathways, emphasizing the role of near-vertical throat clusters. • Growth line orientation in coral reef limestone is the primary factor controlling macroscopic slurry infiltration behavior. • CT scanning before and after infiltration provides critical insights into pore structure and connectivity changes.
