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® RM 470 Slump Enhancer is a revolutionary advancement in time-activated polycarboxylate-based technology.
- Flexible agree of slump retention through adaptable dosing
- Increases slump life with minimal impact on set times
- Better control of operational costs
TYTRO® RM 471 is a high performance, liquid rheology-modifying admixture based on a highly purified mineral using a patented process that creates pure, uniformly-sized, rod-shape particles, to improve cohesion, adhesion and early strength development to shotcrete.
- Eliminates silica fume
- Improves sprayability
- Reduces rebound losses
- Temporary and permanent rock support in tunnels
- Rock support in mining
- Slope stabilisation
TYTRO® SA 520 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 – highly active formulation for lowest dosages
- Reduced excavation downtime – increased adhesion and faster setting
- Improved strength – increased early age strength development without compromising later age strength
The dosage of TYTRO® SA 530 can vary based on the type of application, mix design, cement type and content, water-tocementitious materials ratio, temperature of the concrete, ambient temperature and temperature of the substrate on which the concrete is to be applied.
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.

TYTRO® WR 170 is a water reducer developed to be used in shotcrete. TYTRO® WR 170 is an aqueous solution of highly purified polycarboxylic acid and carbohydrates.
- TYTRO® WR 170 is suitable for shotcrete with a range wide range of strengths.
- TYTRO® WR 170 can be used in shotcrete to provide initial water cut and dispersion. A Type HWR (Superplasticizer) like TYTRO® WR 172 is used in combination with TYTRO® WR 170 to provide the required final slump for spraying.
- TYTRO® WR 170 is batched at the concrete plant and is dispensed into the mix with the initial mix water.
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
- Ideal for use in wet mix shotcrete applications to produce high early strengths
TYTRO® WR 172 is the latest technology in the development of high range water-reducing superplasticising admixtures.
- Produces very high slump shotcrete at low water cement ratios
- Eliminates the need for on-site addition
- Superior slump retention without retardation
- Allows shotcrete to be produced over a wide range of strengths, at low water-cement ratios with high placement slumps
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.
