Abstract: Desulphogypsum soil cemedine is a new type of soil cementing agent. Based on a large number of lab tests on the stabilized soil cemented with ordinary portland cement and desulphogypsum soil cemedine respectively, the data on unconfined compressive strength, shearing strength, compressive modulus and permeability coefficient of these two kinds of stabilized soil are provided. By contrasting and analyzing the data, it shows that the stabilized soil cemented with desulphogypsum soil cemedine is much better than that stabilized with ordinary portland cement in compressive strength and shear strength, and the property of compressibility and permeability can satisfy the engineering demand. Meanwhile, the relationships among strength, curing age, mixing ratio and water content are verified, and the mechanism is also analyzed. It is demanstrated that the desulphogypsum soil cemedine used to deep mixing piles is suitable for engineering especially in soft soil regions with high moisture content.
