TYTRO® WR 157 is a polycarboxylate-based high-range water-reducing admixture specifically formulated to provide prolonged workability, excellent plasticity, and extended slump life in underground shotcrete applications. Featuring the latest in the polycarboxylate technology, TYTRO® WR 157 provides superior water reducing performance to shotcrete.
TYTRO® Shotcrete System
We've developed the industry's only complete shotcrete system
For tunneling contractors, mining companies and any team involved in underground construction, we've developed the industry's only comprehensive shotcrete system.
Components within TYTRO® Shotcrete System are specially formulated to work together. They provide shotcrete applicators with every product they need to handle the most technically demanding underground projects.
Our full range of innovative products includes:
- High-range water reducers: TYTRO® WR
- Hydration control: TYTRO® HC
- Air-entraining: TYTRO® AE
- Rheology modifiers: TYTRO® RM
- Rheology control: TYTRO® RC
- Set accelerators: TYTRO® SA
Plus, our system features STRUX® BT50 synthetic fiber that, unlike steel, won't corrode and is easier to handle during mixing.
It's all in the mix: our shotcrete products are optimized to reduce costs and cycle times
The TYTRO® Shotcrete System lowers operational costs by boosting productivity and minimizing waste and downtime. We've designed all TYTRO® products to meet the toughest performance and safety standards for underground construction.
TYTRO® products save time and money by providing:
Faster early strength
Enhanced bond to rock
Increased pumpability and sprayablity for optimal spray concrete
Quicker thickness buildup
Rebound rates of 5-8%
Our shotcrete system helps producers optimize their mixes to minimize material costs. The 99% silica purity of TYTRO® RC admixtures, for example, sharply reduces shotcrete waste for less material costs.
Expert training, support and technology complete the system
Our Blue360sm Field Advantage team provides education and support across the globe. Our team delivers custom education to help applicators increase productivity, safety and quality on any type of underground construction project. Applicators can count on our remote technical support to troubleshoot field issues and reduce downtime.
Also, our team offers quality control training and field diagnostics to measure shotcrete quality and ensure continuous performance improvement on-site.

TYTRO® WR 157 - High-range water reducers
TYTRO® HC 250 - Hydration control
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® AE 254 - Air-entraining
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® RM - Rheology modifiers
TYTRO® RM rheology modifying and mix-enhancing admixtures are formulated to improve the pumpability and sprayability of the shotcrete mix.
TYTRO® RC - Rheology control
TYTRO® RC innovative rheology control admixtures are designed to reduce our customers’ installed material cost when used as a replacement for silica fume or other pozzolanic materials.
TYTRO® SA 530 - Set accelerators
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.
STRUX® BT50 - Synthetic fiber
STRUX® BT50 is our 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.
