Products 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.
Products performance
- The product has a high water reduction rate of 15-30% and can significantly increase the strength of concrete at various ages.
- Adding this product with the same construction conditions and design strength can save 10-20% of cement.
- It has good adaptability to Portland cement, ordinary Portland cement, slag Portland cement and fly ash Portland cement.
- It can significantly improve the durability of concrete impermeability and antifreeze.
- Low alkali content, per cubic meter of concrete (the amount of cement is 400KG), the alkali content (combined Na2O) increased by adding this agent is less than 1KG.
- In accordance with the use of aliphatic water reducing agent and sulfamate water reducing agent, the effect and plasticity of the product are obviously improved.
- This product can be widely used in concrete, construction, highways, bridges, airports, ports, terminals, prefabricated concrete and other concrete projects.
