Sodium Naphthalene Sulphonate Formaldehyde-B/Naphthalene Formaldehyde Sulphonate/Fdn

Sodium naphthalene sulfonate powder contain 5%, 10%, 18% three different ingredient, (light) brown power. Because of its stable performance, non-poisonous, odorless, non-flammable, non-corrosive to steel bars and much better than Sodium Lignosulphonate and Calcium Lignosulphonate series product, it is more and more popular in construction industry. The main properties is high-efficient water reducing, increasing cement paste fluidity, and improving concrete strength etc.

Main Specifications:

Items&Indicator	SNF-5%	SNF-10%	SNF-18%

Features:
1. The concrete strength and slump in substantially the same, can reduce the amount of cement 10-25%.
2. In the same water-cement ratio, the concrete initial slump raise more than 10cm water reduction rate of 15-25%.
3. The concrete has a significant early strength, the reinforcing effect, the strength of improved rate of 20-60%.
4. To improve the workability of concrete, improve the physical and mechanical properties of concrete.
5. Good adaptability to various cement, and other various types of concrete admixtures compatibility is good.
6. Is particularly suitable for use in the following concrete projects: flowing concrete, plastic concrete, steam curing concrete, impervious concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength ultra-high strength concrete .
7. When the loss of a large concrete slump, slump loss of nearly half an hour to 40%.High water reducing rate (15% ~ 25%), not bleed air, small influence on the setting time, and cement adaptability is relatively good, can be used with other complex admixture of, the price is relatively cheap

Usages:
Sodium naphthalene sulfonate formaldehyde produces concrete with extremely workable characteristics referred to as high slump.PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
Sodium naphthalene sulfonate Formaldehyde is ideal for use in prestress, precast,bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
