This study presents the development of a micro-particle grouting material based on Portland cement Type III (PCIII), silica fume (SF), and sodium silicate for permeation grouting in sandy soil stabilization. The fine particle size of the composite allows effective penetration into sand voids, leading to improved mechanical performance and reduced permeability. A systematic experimental program was conducted to investigate the influence of SF replacement levels and water-to-binder (W/B) ratios on fresh and hardened properties. Flowability, bleeding, setting time, and compressive strength were evaluated, while microstructural characteristics were examined using SEM, XRD, BET, and FTIR analyses.
