TYTRO® Shotcrete system
Advanced. Efficient. Reliable.
Full system delivering lower installed cost, reduced cycle times and superior performance.
TYTRO® is a comprehensive admixture system to reduce shotcrete installed costs, minimise excavation downtime and enhance performance. The system consists of macro fibres 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 optimise mix cost, minimise rebound and accelerate cycle times to boost output while achieving desired technical performance and meeting the highest safety standards.

TYTRO® AE 225 is specially formulated for use as an air-entraining admixture for shotcrete and is manufactured under rigid control which provides uniform, predictable performance. It is supplied ready-to-use and does not require premixing with water.
- Workability is improved
- Durability is increased
- TYTRO® AE 225 is used in shotcrete applications.
TYTRO® AE 270 admixture is an aqueous solution of a complex mixture of organic acid salts.
- Workability is improved
- Durability is increased
- TYTRO® AE 270 is used in shotcrete applications.
TYTRO® 430 RC is a high performance, liquid rheology-control admixture based on nanometric colloidal silica formulated to improve cohesion, adhesion and early strength development to shotcrete.
- Reduces or eliminates silica fume
- Improves sprayability
- Reduces rebound losses
- Temporary and permanent rock support in tunnels
- Rock support in mining
- Slope stabilisation
TYTRO® SA 535 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.
- Efficient dosage rate
- Reduced excavation downtime
- Greater improved strength
- Temporary and permanent rock support in tunnels
- Underground rock support in mining
- Slope stabilisation
TYTRO® WR 171 is a high range water reducer commonly referred to as a superplasticiser. It is an aqueous solution of a modified naphthalene sulphonate.
- Produces very high slump shotcrete at low water cement ratios
- Eliminates the need for on-site addition
- Extremely versatile superplasticiser for a wide range of applications
- TYTRO® WR 171 is suitable for shotcrete with a wide range of strengths eliminating the need for other superplasticisers.
A global team of field technical specialists providing the highest level of performance and support
From the smallest to the largest, the simplest to the most complex underground projects, every project has its own individual challenges. Our field underground shotcrete specialists work closely with customers to help them achieve safer and more efficient shotcrete operations by deploying market-leading technologies, advanced resources (ranging from rapid diagnostic tools to on-site monitoring systems) and unmatched mix optimisation capabilities with expert site support and training.
Efficient ground support operations
TYTRO® offers speciality shotcrete admixtures that are formulated for shotcrete mixes to achieve superior flow, enhanced pumpability and sprayability and prolonged slump life (up to 72 hours) to accommodate logistical and operational needs of every project.
Reduced cycle times
The latest generation of TYTRO® high-performance alkali free accelerators minimise re-entry times by shortening setting time and providing very high early strength.
Thicker passes with less rebound
Featuring the latest in nanotechnology, TYTRO® RC Pozzolanic-based rheology control agent brings rebound rates to single digits (6-8%) and allows placement of 2X larger layer thickness in one single pass by providing superior bond to rock substrate and enhanced cohesion.
Optimal mix design
Our world-class laboratory resources and field technical specialists provide customised mix designs to achieve performance requirements and ensure minimum cost.
