Abstract: The stabilization of loess can make the water physical properties of loess change, improve the structure of loess, and improve the compressive strength of loess. In this paper, the ratio of lime and soil is 7:1, water solid ratio is 0.38:1, the concentration of the proportion is 72.7%, after the mixed slurry of loess, solidifying powder and water curing, we can find the compressive strength of the age of 9 days has been more than 1MPa, the maximum com-pressive strength has reached 1.28MPa, the maximum compressive strength of the age of 28 days has reached 3.54MPa which were more than ten times than the old loess strength. In the comparison experimentthe of cement and solid powder of lime soil ratio 4:1, compare the age of 11 days with age of 20 days, the compressive strength is more than two times than the cement, the hydrophilic loess converts to hydrophobic material by solidifying powder curing, the disintegration will not occur when it encounters water and the intensity in the water increases with time..
