Abstract: Aqueous silica nanoparticle suspensions are widely available and used within a number of industries. A relatively new area of application is as a grouting material for sealing narrow fractures in tunnels. While silica sols/gels have been used successfully to grout sections of tunnels the continued reliability of the grouting requires knowledge of gel formation, long time stability and functionality. Although much research has been done for silica nanoparticle interactions with monovalent cations... more
