Cement-Stabilized Subgrade (CSS) Soils

The degree of improvement depends on the quantity of cement used and the type of soil. Therefore, by the addition of varying amounts of cement, it is possible to produce cement-stabilized subgrade with a wide range of engineering properties. Typical 7-day unconfined compressive strengths (UCS) for CSS range from 100 to 300 psi (0.7 to 2.1 MPa).
