Abstract:

 The cement mixing ratio  was respectively selected as 5％, 10％, 15％, 20％, and the curing age was respectively selected as 7, 14, 21, 28d to put forth the uniaxial compression test. The value of unconfined compressive strength and the change law of stressstrain curve for cement soil was obtained. Finally, the influence of cement mixing ratio and small age on mechanical behavior of cement soil were quantitatively analyzed, and the mathematical expression of stressstrain relation curve was granted, which could  provide science foundation for applying cement soil into irrigation channel liner impervious engineering and civil construction engineering in the middle area of Inner Mongolian Autonomous Region.

Key words: unconfined compressive strength; , age, cement soil, cement , mixing ratio, stressstrain relation curve
