Sodium Naphthalene Formaldehyde Concrete - China

SODIUM NAPHTHALENE FORMALDEHYDE

General Description:

SNF' s 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 accelerate project mould turnover and construction speed, and save cement, and also improve cement mobility and workability.

SNF is a high range concrete admixture of concrete cast- in- place, prefabricating, pump and curing.

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.

5 - The agent can be combined with other externally applied agents if pilot devement or laboratory experiment succeeds.

Application:

SNF has a good adaptability to various cements and it is not 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 civil building, prestressing force component and high range concrete etc.
