Experimental Investigations of Colloidal Silica Grouting in Porous Media
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 135, Issue 5
Abstract
This paper presents the results of an experimental investigation performed to understand the processes influencing the injection of colloidal silica grout into porous media. Based on the combined analysis of grout injection pressures and the visually observed grout distribution patterns, three major processes, gelation, shear, and viscous fingering, have been identified to occur during grout injection. The results demonstrate the dynamic interplay between grout viscosity variations and the resulting flow instabilities.
