Experimental Study on Strength and Deformation Characteristics of Cement Soil Under Wet and Dry Cycle

Jiangsu province, located in the middle and lower reaches of Yangtze River, suffers from rainfall temperature humidity changes, which has a significant impact on structure road base foundation soil cyclic wet dry cycle process, impacting endangering strength deformation characteristics soil. This paper studies filling Shanghai-Shaanxi Expressway for change rules cement improved under cycle, discusses influence admixture, age number cycles The results show that higher admixture longer curing age, compressive cured soil; tends to slow down gradually growth with increase slows obviously after 28 d; process will have an irreversible soil, slowing or even reversing rate can be reduced by increasing admixture.
