Abstract: Mechanical parameters of cement soil will be affected by the environment of salt solution during the curing process. Through strength and micro test, the variation law of compressive strength of cement soil under different corrosion grades is discussed. Results show that with the increase of sulfate ion concentration, the compressive strength increases first and then decreases, and the compressive strength will be less than that of clean water under strong corrosion grade. With the decrease of magnesium concentration, the pH value increases, soil compressive strength is increasing. There is a good linear relationship between resistivity and compressive strength of cement soil, and there is a positive correlation between the two indices.

Key words: cement soil, salt solution, resistivity, compressive strength
