    Abstract

    The aim of this study is to investigate the groutability of a microfine cement and silica fume mix grout into fine to medium sands. The basic rheological properties of the cement and silica fume mix suspension (microfine cement: 90 % of solids by weight and silica fume: 10 % of solids by weight) with water/solid ratio of 1.0 are first determined. In addition, penetration performance of the suspension into fine to medium sand specimens having different relative densities is investigated. Unconfined compression and permeability tests were performed on the grouted specimens. It is found that the unconfined compressive strengths of sand specimens permeated the grout mix were higher than those of sand specimens permeated with cement but without silica fume additive. Permeability tests on specimens permeated with cement/silica fume revealed that the permeability in these specimens is lower than that of specimens permeated with cement only.
