The Effect of Cementation on the Mechanical Properties of Muddy Soil of East-South Coastal Area of China

Abstract:

Based on characteristic of the muddy soil residing in east-south coastal area of China, the effect of cement grade, cement-mixing ration and cement type on mechanical properties of cement-soil was carried out in this paper. The results show that cement-soil increases obviously with increasing of hydration age for different cement types. At early hydration age, strength of cement-soil increases quickly. And at the age of 28d~90d, strength of cement-soil still show quite obvious increasing, but increase rate is slow. Increasing cement-mixing ratio improve strength of cement-soil obviously and 0.15~0.20 cement-mixing ratio is suitable to use. Higher cement grade can bring higher strength of cement-soil. Early strength of cement-soil solidified with P.S32.5 increases slowly, but the middle and late stage strength of cement-soil solidified with P.S32.5 increase quickly. The solidification effect of P.S 32.5 is better than that of AEC32.5 and P.MSR32.5.
