Sodium Naphthalene Formaldehyde Admixture for Concrete

SNF full name is Sodium Naphthalene Sulfonate formaldehyde condensate. Its high purity makes cement particles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability. SNF is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing.

Sodium Naphthalene Formaldehyde has two Specs as flws:

1)Sodium Sulphate 5%
2)Sodium Sulphate 18%

Appearance yellow beige powder
Fluidness (mm) 240 min
Water exudation rate: 90%max
Gas content 3.0%max
Solid content 90%min
Sodium Sulphate 5%max / 18%max
Cl 1.0%max

Technical features & adaptability: 
1. Mixing amount: 0. 5-1. 0% of cementing materials, reducing rate: 20-30%
2. Keeping concrete strength intact & mixing this product, cement saving amount can reach 15-20%
3. Mixing this product 0. 7% (solid content) , slump constant increases above 10cm
4. Adapting to high strength, early strength, flowing, prefabricating & curing and prestressing force concretes etc.
Before using this product, please read precaution first.

SNF has a good adaptability to various cements and it is no erodent to reinforcing bar and nonpoisonous and pollution-free. SNF has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial and civil building, prestressing force component and high range concrete etc.
