According to recent research published in the journal Tunnelling and Underground Space Technology, "A recently introduced non-cementitious grout silica sol is a refined product of colloidal silica, where the particle sizes have been reduced to between 5 and 100 nm. Laboratory tests were performed to determine the behaviour of silica sol as a permeation grout in hard rock."
"The tests have involved methods Such as fall-cone, unconfined compression, triaxial, and oedometer tests. Samples were tested at different time intervals and in different storage environments. the initial strength of silica sol, a few kPa, increases over time. Silica sol has a ductile ...
