www.concreteproducts.com January 2018 • 67 INNOVATIONS REPORT GCP TYTRO SYSTEM Shown here in an early field application, the Tytro Shotcrete System offers these GCP-cited benefits against silica fume alternatives: high dosage efficiency; enhanced sprayability and improved cohesion; waste minimization through lower rebound and dust; reduced cycle times owing to greater layer thickness attained in a single pass; accelerated strength development; lower permeability and higher water penetra- tion resistance; handling ease and safety; more consistent quality; and, storage efficiency in the absence of silo requirements. achieved through mix optimization, waste minimization and shorter cycle times; and, affords faster construction area re-entry times due to more rapid early age strength development at equal accelerator dosage rate. Joining RC in the Tytro Shotcrete System are GCP's Strux 2-in. synthetic macro-fiber plus these companion agents: WR high-range water reducer; HC hydration control, extending mix working life up to 72 hours; SA, an alkali-free set accelerator formulated to provide high early strength at low dosage rates; AE air entraining admixture; and, RM, a rheology modifier to improve pumpability and spraying sequences. — GCP Applied Technologies, Cambridge, Mass., www.gcpat. com/shotcrete PHOTO: GCP
