MasterRoc SA 193

Alkali-free, Liquid High Performance Set Accelerator for Sprayed Concrete

Material Description

• MasterRoc® SA 193 is a high-performance, suspension type alkali-free set accelerator for sprayed concrete.

• The dosage can be varied to the desired setting and hardening requirements.

Areas of Application

• Temporary and permanent ground support in tunneling and mining

• Slope stabilization

• Also suitable for acceleration of cementitious grouts, such as for annulus grout in TBM tunnels, cemented ground injection and foam concrete

• Applications where higher early strength and larger layer thickness in a single application is required

Characteristics and Benefits

• MasterRoc® SA 193 is ideally suited for wet mix sprayed concrete for ground support

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

• The unique product formulation provides fast setting, continuous early-age strength development, high durability and good long-term strength

• Very low dust generation during application and therefore a good working environment

• Possibility of low rebound applications when using the correct nozzle angle and distance

• Non-aggressive properties provide improved working safety, reduced environmental impact and lower handling costs

• Alkali-free

• Chloride free: no impact on reinforcement steel
