DAFL – Dalton Alkali Free shotcreting Liquid Accelerator
DAFL- Dalton Alkali Free shotcreting Liquid Accelerator
Dalton AFL is an alkali-free accelerator available in liquid form for use with sprayed concrete for guniting/shotcreting.
It is a liquid additive whose dosage can be varied to the desired setting and hardening times.
- Free of chlorides, no danger to steel reinforcement and steel fibres
- Very fast setting of shotcrete mixes
- Large reduction in rebound
- Low viscosity – less pumping problems
- Improves bond of shotcrete to rock and concrete, making overhead spray easier.
- Instant setting in guniting or shotcreting of support lining and waterproofing of tunnels
- Securing of rock in tunnel mine construction
- Rock and slope stabilization
- It is generally dosed at between 3-10 % by weight of cement directly in the shotcreting water pump for wet-mix spraying process. The most effective dosage must be determined by site trials.
- High quality shotcrete for general construction work.
- It is generally dosed at between 3-10 % by weight of cement directly in the shotcreting water pump for wet-mix spraying process. The most effective dosage must be determined by site trials.
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
DLSA – Silicate Base Shotcreting Accelerator
DLSA- Silicate Base Shotcreting Accelerator
Dalton LSA is a modified specials-grade liquid silicate accelerator and waterproofing compound for
guniting/shotcreting.
- Increases internal cohesion and adhesion of shotcrete
- Reduced significantly the rebound of the gun mix
- Thick layers can be applied in one application
- Produce a high strength and dense shotcrete
- Dust reductions
Packaging: DAFL and DLSA comes in 250 kg drum. Storage: Store DAFL and DLSA in dry conditions at temperatures between +10°C and +30°C. Protect from direct sunlight and frost.
- Production of permanent gunite and shotcrete elements
- Protect construction pits and subterrain excavations
- Rock and soil stabilization
- It is generally dosed at between 3-10 % by weight of cement directly in shotcreting water pump. The most effective dosage must be determined by site trials.
