Experimental study of cement strength grade and mixing ratio to cement-soil mechanical properties

Cement-soil mixing method is commonly used in strengthening soft soil foundation, the choice of cement strength grade and mixing ratio influence cement-soil strength and cost of engineering sales. Based on the characteristics of China southeast coastal silt soil, mechanical properties of cement-soil was studied in the condition of different strength grade. In addition, a function was proposed to predict cement quantity for different strength grade in the same ground compressive strength requirement, it has important significance to optimal proportioning and control engineering cost.
