QUICKSET AF 267
QUICKSET AF267 is a ultra high performance alkali-free set accelerator for sprayed concrete to produce shotcrete characterised by rapid setting times and very quick strength development of its strength after only a very short curing time. Dosage can be varied to the desired setting and hardening times
Specification Compiles
- ASTM C 1141/C 1141M, TypesI, II, Grade 9, Class A
- High early strength development
- Alkali Free
- Lower rebound during application
- Chloride Free
- Reduction in dust
- No pollution for surface and ground water
- Securing tunnels during boring applications
- Shotcrete inner lining
- Slope stabilization
- Rock support in mining
- Where exceptionally high early strength, good final strength and extremely thick layers are required
- Suitable for acceleration of cementitious grouts, such as used in TBM tunnel linings, cement ground injection and foam concrete backfill operations
