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.

Features and Benefits

Non-toxic, non-irritating and no corrosion to steel bars

High water reducing rate: up to 25%

Strengthening ability

Improving concrete durability and impermeability

Appropriate setting time

Good compatibility with various types of cement

Dosage and Usage

1. The dosage is about 0.5 ~ 1.5% of cementitious materials, actual usage needs to be confirmed by the test.

2. Due to the adaptive differences between different types of the cement and admixtures. The adaptive test of cement and admixture should be done before using or changing the cement type.

Packaging, transport and storage

1. The powder product is packed with 25 ± 0.25kg laminating woven bag. Packaging specifications should meet the user requirements.

2. Powder product is easy to soluble in water, liquid dilution will affect the effective concentration of the product, transport and storage should be noted that the anti-leaching, avoid moisture, direct sunlight, kept under seal and away from open flame at the room temperature or during the transport.

3. In the case of good storage conditions, valid period is three years. If it is more than 3 years, rechecking is needed for using continually.
