Soil In this study, granular soil material was stabilized by using injection method under laboratory conditions. As additive, the mixtures of silica fume and lime were used for this experimental study. The mixtures that are turned into slurries by adding water were injected to the granular soil media prepared in the cylindrical plastic mold. Then these samples were cured for 1, 7 and 28 days. The end of curing time, all samples were tested in accordance with unconfined compressive tests and obtained unconfined compressive strength values of injected granular soil samples were compared with that of the natural granular soil samples. As a result, it is concluded that the he mixtures of silica fume and lime can be successfully used for the improve of granular soils in the geotechnical applications.
