Abstract (EN): This paper will focus on the sensitivity of strength and stiffness properties of silty-sands, from granitic residual soil, which can be converted to a highly improved material if stabilized with cement. The study of soil stabilization with cement demands to quantify the influence of the cement percentage, porosity and water content adopted in the admixing process for different stresses and physical states. Firstly, this influence was quantified in terms of the unconfined strength and maximum deformability modulus executing unconfined compression tests as well as seismic wave velocities measurements in thoroughly controlled conditions in laboratory, varying the factors indicated above. Then, drained triaxial tests with very precise instrumentation were performed in some specimens with such a cement percentage and water content fixing the relationship between the void ratio and the volume of cement.
