Advanced Systems for High Performance Sprayed Concrete
High-quality, durable shotcrete has become a vital component of ground support and stabilisation in tunnelling and mining. With shotcrete’s relatively low price, wet mix sprayed tunnel linings create state-of-the-art, monolithic/composite structures with a substantial reduction in cost and time. This also lowers health risks, increasing worker safety and reducing the environmental impact versus conventional concrete placement.
Our concrete admixture technologies enhance the performance, hydration control, and viscosity of sprayed concrete to exceed customer needs.
MasterRoc SA: The fast-setting alkali-free accelerator series (MasterRoc SA) produces sprayed concrete with early and long-term strength. Structural reinforcing fibres improve load absorption, reduce crack propagation, and increase durability. We offer chloride-free liquid admixtures to enhance concrete's plasticity and hardened properties.
MasterRoc HCA 20: MasterRoc HCA is a cement hydration control system for wet and dry sprayed concrete applications, maintaining pot life for up to 72 hours, ensuring flexible site logistics.
MasterRoc MS 699: Adding microsilica (MasterRoc MS) reduces permeability, increasing density, strength, and durability of hardened sprayed concrete, while improving pumpability and workability. Master Builders Solutions offers a wide range of shotcrete solutions for various applications. For more information, speak with one of our specialists today.
MasterFiber 141: MasterFiber 141 is an embossed fibre made from polyolefin polymers for use in spray and cast in-situ concrete mixes. It enhances durability by increasing crack resistance and energy absorption.
