Product Description

High Performance Naphthalene Superplasticizer For Concrete CAS No. 9008-63-3

Naphthalene superplasticizer

Chemical name:
β Sodium naphthyl sulfonate formaldehyde condensate.
Molecular formula:
(c10h6ch2naso3) n, n is mainly 9-12.


Naphthalene superplasticizer has good adaptability to various cements and improves the operability of concrete.FDN 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.
It is widely used in concrete engineering: highway, railway, bridge, tunnel, power station, dam, high-rise building and other projects.It has good dispersion, water reduction and early-strength effect.Adding naphthalene series superplasticizer into ordinary concrete can improve the physical and chemical properties of concrete, improve the concrete strength, construction speed, project quality, technology and working conditions.

1. early strength admixture - improve construction progress;
2. retarding admixture - prevent cracking of large infrastructure such as airports and bridges;
3. pumping type admixture - transported by pump, such as high-rise buildings;
4. antifreeze admixture - used for winter construction.

FDN-A High concentration product with sodium sulfate content no more than 5 percent.
FDN-AI Middle concentration product with sodium sulfate content no more than 10 percent.
FDN-AII Low concentration product with sodium sulfate content no more than 18 percent.
FDN-23 sodium sulfate content no more than 23 percent,cheapest type to save cost.

Usage method:
--Powder 0.5%-1.0%, recommended dosage 0.75%;
--Liquid is 1.0%-2.0%, and the recommended mixing amount is 1.5%. The mixing amount can be appropriately increased according to the grade of concrete.
--Each batch of goods must be tested to meet the engineering requirements before use.

1. As the requirement of engineer,the dosage can be adjusted after testing.
2. It can be put into blender with mixing water,making mixing before concrete pouring,the plasticizing effect could be better.

Characteristics:
1. This product is non-toxic,non-inflammable with stable shape.No corrosion on steel bars. It is applicable for precast concrete, cast-in-place concrete, reinforced concrete, prestressed reinforced concrete, etc. in various projects.

2.Without air entraining and also has smooth and beautiful appearance.
3. The low alkalinity will not give rise to the alkali aggregate reaction.
4. The water reducing ratio is 15 to 30 percent. It can also improve the fluidity of blended material with the concrete slump at 18 to 25cm.
5. It can also have strong dispersion for cement and can effectively improve the workability of blended material to make sure the concrete mixture is easy to pouring and vibrating.
6. It can improve the strength of concrete for 60 to 100 percent with in 1 to 7 days.
