Sodium Naphthalene Sulfonate Formaldehyde
NZY-FN has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete. As the main master batch of various kinds of compound concrete admixture, it could also produce series products of concrete admixture which can be suitable for all kinds of project requirement through compounding with other kinds of admixture. This product can contribute to the improvement of project quality and construction efficiency and the reduction of construction cost. It can also improve the process of works.
■ Scope of application
1. It can be applied to cast-in-situ, prefabricating, prestressed steel concrete and fly ash concrete, etc.
2. It is suitable for configurating early strength, high strength, high impermeability, self-fcompaction and high durability concrete.
3. It can be applied to self-cured and vapor-cured concrete project and products.
4. It can used to configurate C30-C60 concrete and also can configurate C70-C80 high strength concrete if the dosage is added and mineral admix-ture is added to the concrete.
