| NEW PRODUCTS & PROCESSES GCP APPLIED TECHNOLOGIES PRESENTS ITS TYTRO ADMIXTURE SYSTEM FOR SHOTCRETE APPLICATIONS The TYTRO® system is designed to deliver lower costs, superior performance, and reduced cycle times During Conexpo, GCP Applied Technologies Inc. (GCP) presented the TYTRO Shotcrete System, a complete stateof the-art admixture solution that makes shotcrete for underground construction better, faster, and less expensive than conventional systems available today. The TYTRO System includes a nanotechnology-based rheology control agent, patented macro-synthetic fibers, and several other newly developed admixtures that enhance productivity of the spraying operation and material performance. “Our TYTRO Shotcrete System provides improved agility and additional capabilities that applicators and global contractors have been demanding for decades,” said Craig Merrill, Vice President of Global Marketing, GCP. The TYTRO Shotcrete System provides underground construction professionals with the capability to reduce operating costs and minimize excavation downtime, without sacrificing performance or relaxing safety standards. The TYTRO Shotcrete System provides faster early strength and enhanced bonding-to-rock with an increased one-pass thickness buildup. The system also minimizes rebound during spraying. Main advantages provided by the TYTRO Shotcrete System compared to conventional mixtures include*: • Up to 10% lower installed cost, achieved through mixture optimization, waste minimization, and shorter cycle times; • Rebound rates reduced to 5 to 8%; • Faster re-entry times, due to more rapid early-age strength development at equal accelerator dosage rate; • Superior bond-to-rock and adhesion between layers, providing greater thickness in one pass; and • More robust and dosage-efficient system. “Our technical specialists have analyzed the unique challenges of underground construction projects to create *Referenced results are based on internal and external test data. Results may vary due to temperature conditions, mixture design, cementitious materials content, and aggregate gradations.
