Model No.:  FDN-A

Product Description

Model NO.: FDN-A Classification: Chemical Additives Appearance: Powder Name: Naphthalene Sulfonate Superplasticizer Sodium Sulfate: Less Than 5% Solid Content: More Than 93% Certification: SGS, ASTM C Trademark: Yuansheng Chemical Origin: Shandong, China Efficacy: Water Reducing Agent Type: Naphthalene Sulfonate Superplasticizer Color: Yellow Brown pH: 7-9 Application: Water Reducing Agent Appearence: Yellow Brown Powder Sample: Free Specification: SGS HS Code: 382440100 Water Reducing Admixture FDN Naphthalene Sulfonic Acid

Product Description
Poly Naphthalene Sulfonate is a high range water reducer; high concentrate naphthalene-based superplasticizer, also named Naphthalene Sulfonate Firmoldehyde Condensate- PNS, FDN etc. SNF is made of naphtyhalene, sulforic acid, formalin and alkali, through sulphuration, dydrolyzation, condensation and neutralization reaction. FDN contains no chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017, GB8076-2008 and GB50119-2003

Main Specifications:
Items&Indicator FDN-A FDN-B FDN-C
Appearance Brown yellow powder
Solid content ≥93%
Sodium sulfate <5% <10% <18%
Chloride <0.3% <0.4% <0.5%
pH 7-9
Static slurry fluidity ≥250mm ≥240mm ≥230mm  

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.
