Cement Sodium Silicate Dual Slurry for Tunnel Sealing

Engineering Challenges of Tunnel Water Inflow and Collapse   In tunnel construction, water inflow and collapse are the two most common and most hazardous geological disasters. Particularly when crossing fault fracture zones, karst-developed areas, or water-rich formations, the sudden influx of groundwater often triggers surrounding rock instability, leading to collapse accidents that seriously threaten construction safety and project progress. Cement-Sodium Silicate dual-fluid grouting technology, with its outstanding advantages of rapid setting, early strength, and good controllability, has become the preferred solution for treating tunnel water inflow and collapse sections.   Technical Principles of Dual-Fluid Grouting   When tunnel sealing-grade Sodium Silicate is mixed with cement slurry in specific proportions, Sodium Silicate reacts with calcium ions in cement hydration products to form calcium silicate gel and silica gel, which bond cement particles together to form high-strengt…
