MasterRoc SA 167

High-Performance Alkali-Free Set Accelerator for Durable, Rapid Sprayed Concrete Applications

How Does MasterRoc SA 167 Work?

MasterRoc SA 167 is a high-performance alkali-free set accelerating admixture for sprayed concrete. It is a liquid whose dosage can be varied to achieve the desired setting and hardening times.

Recommended Uses:

• Temporary and permanent rock support in tunnels

• Rock support in mining

• In poor and wet ground conditions

• Slope stabilisation

• Also suitable for the acceleration of cementitious grouts, such as those used in TBM tunnel linings, cement ground injection, and foam concrete backfill operations

What Are the Unique Features of MasterRoc SA 167?

MasterRoc SA 167 is ideally suited for wet mix sprayed concrete support because:

• The quick setting properties allow rapid work progress and the ability to construct thick sprayed concrete linings via layered application during one construction sequence

• The unique product formulation provides an extremely fast setting coupled with continual early-age strength development

What Are the Benefits of MasterRoc SA 167?

• Good long-term strength and durability are achieved

• MasterRoc SA 167 is a liquid product and thus provides easy handling as well as facilitating accurate addition to the concrete

• Very low dust production and therefore a safe and suitable working environment

• Since the product is non-aggressive, it provides improved working safety, reduced environmental impact, and lower handling costs
