S/2 SYSTEM
Plasticising setting accelerator
for shotcrete
DESCRIPTION
Two-component plasticising additive with high cohesiveness and thixotropicity for shotcrete with high mechanical performance.
S/2 SYSTEM consists of a Component A, a plasticising powder additive, to be mixed in the concrete mix and a Component B, a sodium silicate-based setting accelerating additive, to be used in the shotcrete phase.
ADVANTAGES
• Greatly improves the plasticity of concrete
• Considerable reduction in concrete rebound
• Considerable reduction in dripping in tunnels
• Increased mechanical performance of shotcrete
APPLICATIONS
• Shotcrete in the presence of water
• Safety of the excavation face
