· Thus, the water content of cement-stabilized soil should lie between the w L and w B. The optimal water content of cement-stabilized soil ( C w (op)) must be in the range to ensure the uniformity, strength, and stiffness. It can be defined as (4) C w (op) = N w L where N is the magnification factor of water content.
