چکیده مقاله
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 effects Due to the fact that in concrete there are no particles passing sieve 200 and thisrestriction does not apply to soil cements, some tests were carried out on the nano SiO2 soil cement matrix because of the meaningful difference between concrete and soilcement The test procedure consists of unconfined compressive test and hydraulicconductivity In these tests, silica fume, nano SiO2 were added to soil cement Theresults show that adding certain amounts of nano SiO2 particles to the soil cementmatrix can improve the compressive strength and reduce permeability and speedhydration reactions in the matrix in presence of nano SiO2 particles
