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.

Overview

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.
