Abstract: A series of electrical resistivity and unconfined compressive strength of hexavalent chromium polluted soil solidified with cement were measured, to reveal the influence of law of age, hexavalent chromium ion content and cement content on unconfined compressive strength and electrical resistivity of the hexavalent chromium polluted soil solidified with cement, and the relationship between the resistivity and unconfined compressive strength. The results show that, unconfined compressive strength and electrical resistivity of hexavalent chromium polluted soil solidified with cement increase with age, and the growth rate is different. The higher the chromium ion content, the lower the unconfined compressive strength and electrical resistivity of hexavalent chromium polluted soil solidified with cement. The more cement content, the greater the unconfined compressive strength of hexavalent chromium polluted soil solidified with cement. The unconfined compressive strength grows with age. When the curing time was shorter, the electrical resistivity of hexavalent chromium polluted soil solidified with cement increased slightly with the increase of cement content in the early age. Unconfined compressive strength(p_u) of samples with 10% cement is approximately linear with electrical resistivity(ρ) of:p_u=0.740 ρ+1.853, R²=0.917. The results of leaching experiments show that the leaching rate of metal decreased and the curing effect becomes better with the increase of curing agent content and curing age. Results of nuclear magnetic resonance revealed that the more hydration producs are embedded in the pore of soil with the increase of cement content, then the pore size range gets smaller. Based on analysis data in micro-pore structures, it shows that the overall smoothness and compactness of the specimens becomes better, and the strength increases with the increase of cement content.
