Abstract
In this study, the colloidal silica grouts (PSG) with novel chemical compositions for permanent reinforcement and water cut-off of the ground were prepared and their engineering charateristics were investigated. The optimum mixing recipes for both homogeneous solution grouts and heterogeneous suspension grouts were investigated and established through many repeated lab tests. The various physical properties(such as compressive strength, durability and syneresis) of the grout gels derived from the colloidal silica were investigated and compared with those of the well-known existing watergalss grouts. The all experimental results showed that the novel colloidal silica grouts(PSG) had greatly excellent performances as permanent grouts, especially in comparison with the existing watergalss grouts.
