Enhancing sandy soil strength, improving bearing capacity, and reducing erosion, making it suitable for construction projects such as roads and foundations. Various physical and chemical methods are available for sand stabilization; however, they may come with limitations such as high costs, environmental impact, and limited depth penetration. This study stands out for its innovative approach, investigating the potential of sodium silicate and calcium chloride as eco-friendly agents for stabilizing sandy soils. Local Jordanian sand known as Sweileh-sand was stabilized using different mixtures of these agents at varying curing times: 0-day, 1-day, 2-days, and 3-days, using a two-step grouting method. The optimal amounts of sodium silicate and calcium chloride were determined through direct shear tests. This approach demonstrates the treatment’s effectiveness in enhancing shear strength and overall soil stability over 3 days. The test results revealed a significant improvement in shear strength parameters of the stabilized sand.
