In many civil engineering problems, soil is stabilized by a combination of binders and water. The success of stabilization is evaluated using seismic tests with measured P-wave velocities. Optimization of process, laboratory testing and data modelling are essential to reduce the costs of the industrial projects. This paper reports the optimized workflow of soil stabilization through evaluated effects from the two factors controlling the development of strength: (1) the ratio between water and binder; (2) the proportions of different binders (cement/slag) were changed experimentally in a mixture of samples to evaluate the strength of soil. The experimental results show an optimal combination of 30% cement and 70% slag with a binder content of 120 kg/m3 and a maximum water binder ratio (w/b) of 5. Such proportions of mixture demonstrated effective soil stabilization both on a pilot test scale and on full scale for industrial works. The correlation between the compressive strength and relative deformation of specimens revealed that strength has the highest values for w/b = 5 and the lowest for w/b = 7. In case of high water content in soil and wet samples, the condition of a w/b ≤ 5 will require a higher amount of binder.

In contemporary geotechnical stabilization applications, there is a simultaneous drive to make applications as light and durable as possible while also preferring the utilization of waste products in soil improvement endeavors due to their dual merits of fostering environmental sustainability and conferring economic benefits. In this study, the use of expanded glass granules as a waste material was implemented to harmonize with this perspective, wherein reference sand and expanded glass granules were systematically mixed in varying proportions by mass and volume. Subsequently, the dynamic behavior of the mixture samples was rigorously assessed through a resonant column test between 0.001 - 0.1% shear strain amplitude and under various cell pressures. The variations in modulus reduction and initial shear modulus of the expanded glass granules added specimens were subjected to analysis, the shear modulus values of the samples mass-prepared (1, 2%) were obtained at least 12% and 21% higher than the reference sand, respectively. Similarly, the shear modulus values of the mixture sample prepared at 2.5% by volume were 20% higher than the reference sand at different effective pressures. The specimens prepared at 5% by volume demonstrate shear modulus values that were akin to those of the reference sand. The shear modulus values of the mixture samples prepared by volume (7.5, 10 and 15%) were found to be relatively lower than those of the reference sand. In the experimental study, it was discovered that the high angle of internal friction of the expanded glass granules exerts an influence on the variation in modulus reduction. According to the results of the experimental study, expanded glass granules show positive results in shallow geotechnical soil stabilization applications.
