DAFP- Alkali Free Shotcreting Powder Accelerator
DAFP- Alkali Free Shotcreting Powder Accelerator
Dalton AFP is an alkali-free accelerator available in powder form for use with sprayed concrete for
guniting/shotcreting. DAFP mixed with gunite tends to reacts and assist the hydration process, resulting in greatly
accelerated strength development within the first 24 hours
- Free of chlorides, no danger to steel reinforcement and steel fibres.
- Temporary and permanent rock support in tunnels and minings
- Very fast setting of shotcrete mixes
- Reduction in rebound
- Better adhesion to areas of slight seepage
- Improves bond of shotcrete to rock and concrete, making overhead spray easier
- It is generally dosed at between 3-10 % by weight of cement directly in the shotcreting water pump for drymix spraying process. The most effective dosage must be determined by site trials.
Packaging: DAFP comes in 25 kg bag Storage: Store DAFP in dry conditions at temperatures between +10°C and +30°C. Protect from direct sunlight and frost. Health and Safety: Dalton Accelerators are non-toxic, non-flammable and eco-friendly. However, it should not be inhaled. Contact with eyes and skin during use should be washed with water immediately. IS Standard: Dalton Accelerators conforms to the specifications of ASTM C 494, type C and IS 9103-1999.
- Instant setting in guniting or shotcreting of support lining
- Waterproofing of tunnels
- Retaining walls, embankment and excavations
- Thin section concrete shells and concrete repair-work
