Shotcrete & Ground Support
Shotcrete is widely used in tunneling to provide immediate ground support and surface stabilization. Its performance is enhanced with admixtures such as accelerators for rapid setting, viscosity modifiers for improved pumpability and spray control, and fibers for structural reinforcement. Hydration control admixtures extend workability, allowing flexible application without compromising strength. Together, these additives ensure fast, safe, and durable shotcrete application in challenging underground conditions.
