Abstract Soil-cement mixture includes cement treated soil and cement stabilized soil. A series of unconfined compressive strength tests of soil-cement mixture specimens after various curing periods were carried out on two typical soils samples with different water contents，in order to analyze the variation of porosity，saturation，and strength of soil-cement mixtures. The test results show that porosity of soil-cement mixtures is depended on the initial water content，the degree of compaction and hydration product output. Saturation decreases with the increase of cement content and curing time. There is a power function relationship between strength and cement content in term of the cement content between 5% and 20%. The strength of soil-cement mixtures grows linearly with the logarithm of curing time. A unique power function relationship well adapts unconfined compressive strength of soil-cement mixtures with a comprehensive parameter，which represents the effect of cement content，curing time and porosity. Test data from the literatures also demonstrate the effectiveness of the proposed comprehensive parameter to represent the strength characterization of soil-cement mixtures.

Key words： soil mechanics cement treated soil cement stabilized soil porosity saturation unconfined compressive strength comprehensive characterization parameter
