Abstract In order to find out the optimal addition ratios of nanometer silica fume, the paper discussed the influence of strength properties of the Cement-Stabilized Soil in different addition ratios’ nanometer materials. Experimental study of different conserved days’ was conducted on Cement-Stabilized Soil with different addition ratios’ nanometer silica fume. By unconfined compressive strength tests of the Cement-Stabilized Soil with the nanometer silica fume, the nanometer silica fume can raise the strength by one to three times than general Cement-Stabilized Soil in the scope of 1% to 2% of nanometer material addition ratio and 8.5% to 20% of cement’s addition ratio. Nanometer silica fume can raise Cement-Stabilized Soil’s early strength, the7 day strength can reach half of 90-day strength. And there exists optimal nanometer material addition ratios as cement addition ratios changing.
