Supplementary Data for: Sodium silicate grouting: mechanisms, environmental impacts, and research directions.

It serves as the foundation for a comparative analysis presented in the associated review paper. The data documents the evolution of silicate research over several decades, summarizing principal mechanistic, chemical, hydraulic, and mechanical insights.

The dataset is organized to highlight: Diverse Grout Formulations: Details on inorganic hardeners and organic activators. Mechanistic Insights: Summaries of gelation kinetics, polymerization, and the impact of pH and temperature on the sol-gel transition. Engineering Properties: Data on unconfined compressive strength (UCS), shear behavior, creep, and permeability reduction in various soil types, including sands, silts, and loess.
