customized mix designs, delivering the most optimized and cost-efficient concrete mix for each project. We also support our customers with world-class site support and training,” said Merrill. The TYTRO Shotcrete System includes the following products: • TYTRO WR: High-range water-reducing admixtures for shotcrete that provide superior flow, prolonged slump life, and excellent plasticity, maximizing strength performance by allowing a lower water-cementitious materials ratio (w/cm); • TYTRO HC: Cement hydration control admixture, extending the working life of shotcrete up to 72 hours; • TYTRO RC: Innovative pozzolan-based rheology control admixture that is designed to reduce installed material cost when used as a replacement for silica fume or other cementitious materials. It provides faster early strength, superior bond to rock, enhanced sprayability, lower rebound, and reduced cycle times; • TYTRO SA: Latest generation of high-performance, alkali-free set accelerators, 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; • STRUX BT: Macro-fibers featuring a patented design developed for underground shotcrete applications and offering superior flexural toughness and post-crack energy absorption; • TYTRO AE: Air-entraining admixture for use in shotcrete mixtures to protect against damage from freezing-andthawing cycles; and • TYTRO RM: Rheology-modifying and mixture-enhancing admixtures formulated to improve the pumpability and sprayability of the shotcrete mixture.
