TYTRO® is a comprehensive admixture system to reduce shotcrete installed costs, minimize excavation downtime and enhance performance. The system consists of macro fibers and admixtures designed to faster achieve early strength, enhance bond to rock substrate and between layers, and deliver high-performance, high-quality shotcrete with minimum rebound and dust.
Shotcrete practitioners and producers stand to gain major savings on material and installation costs by incorporating TYTRO®. Users can optimize mix cost, minimize rebound, and accelerate cycle times to boost output while achieving desired technical performance and meeting the highest safety standards.

STRUX® 90/40 synthetic macro fibers are a unique form of high strength, high modulus synthetic reinforcement that is evenly distributed throughout the concrete matrix. The macro fibers add toughness, impact and fatigue resistance to concrete and improve residual strength and durability. Unlike traditional microfiber reinforcement, STRUX® 90/40 macro fibers are specifically engineered to provide post-crack control performance.
STRUX® 90/40 macro fibers may be used in a variety of ready mix, precast and shotcrete applications including slab-on-ground flooring, overlays, pavements, bridge decks, composite steel floor deck assemblies, mass concrete, thin-walled precast elements (septic tanks, vaults, walls, etc.), tunnel linings, pool construction and slope stabilization.
STRUX® BT50 synthetic macro fiber reinforcement is a high strength, high modulus synthetic macro reinforcement that imparts toughness, impact and fatigue properties to concrete. STRUX® BT50 is a patented engineered design providing superior post-crack control performance with a broad range of applications.
STRUX® BT50 Synthetic Macro Fibers are engineered for ease of use, excellent dispersion and finishability in slab-on-ground flooring applications.
TYTRO® AE 250 is an air-entraining admixture which generates a highly stable air-void system for increased protection against damage from freezing and thawing, severe weathering, or de-icer chemicals.
TYTRO® AE 254 is an air-entraining admixture which generates a highly stable air-void system for increased protection against damage from freezing and thawing, severe weathering, or de-icer chemicals.
TYTRO® FR 850 macro fibers are GCP Applied Technologies’ latest generation synthetic-based macro-fiber, featuring a patented high strength, high modulus design providing superior flexural toughness and post-crack performance in underground shotcrete applications.
TYTRO® HC 250 is a ready-to-use, liquid, non chloride solution specifically designed to control and stabilize the cement hydration of shotcrete for long periods (up to 72 hours) without negatively influencing the quality of shotcrete.
TYTRO® MF 120 is an aqueous water-reducing admixture specifically formulated to enhance the properties of cementitious mine backfill.
TYTRO® MF 120 is used in all mine backfill applications where it is desired to minimize the binder content yet maintaining workability.
TYTRO® RC 430 is a rheology-controlling admixture specifically formulated to improve sprayability and pumpability characteristics of shotcrete by increasing cohesion, provide superior bond to rock substrate, faster strength development, and minimum rebound and dust to tunnels and underground mining shotcrete applications.
TYTRO® RM rheology modifying and mix-enhancing admixtures are formulated to improve the pumpability and sprayability of the shotcrete mix.
TYTRO® SA 528 is a high-performance, alkali-free set accelerator specifically formulated to provide high early strength at low dosage rates and improve productivity by shortening the time of setting without compromising long-term strength and durability
TYTRO® SA 530 is a high-performance, alkali-free set accelerator specifically formulated to provide high early strength at low dosage rates and improve productivity by shortening the time of setting without compromising long-term strength and durability.
