Effects of Silica fume and nanosilica onCompression of soil cement

Soil cement is a mixture of Portland cement, soil and water, in which hydration of cementand compaction causes the materials’ constituents to bond together making a dense anddurable composition with low permeability and abrasion resistant. Since most of therecent researches are focused on the addition of nano-SiO2 on concrete, in this paper ithas been attempted to use nano-SiO2 particles in soil-cement and observe the effectsbecause of the meaningful difference between concrete and soil-cement. The testprocedure consists of moisture-dry density. In these tests, silica fumenano-SiO2 wereadded to soil-cement. The results show that adding certain amounts of nano-SiO2particles to the soil-cement with silica products can improve the unconfined compressionstrength of soil cement.
