Product Description:

Naphthalene high concentration superplasticizer 

Naphthalene sulfonate formaldehyde condensate chemical additives  compared with naphthalene 

superplasticizer has higher water reducing rates, higher active ingredient content. According to the

temperature conditions and technical requirements of the project, using a prototype or composite

 measures can be formulated various types of highstrength concrete C80 below. Adaptability of 

cement, in taking appropriate measures to meet the technical requirements of all types of 

concrete throughout the year. 

■ 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.

■ Main performance and characteristics
1. This product is non-toxic,non-inflammable with stable shape. It does not have corrosion effect on steel

2. The concrete does not have air entraining effect and also has smooth and beautiful appearance.
3. It is a high concentration product with sodium sulfate content on more than 5 percent. low concentration

 product with sodium sulfate content no more than 18 percent. The low alkalinity will not give rise to the 

alkaliaggregate reaction.
4. The water reducing uatio 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. high concentration product can improve the strength of it for 20 to 40 percent in 28 days. low 
concentration product can improve the strength of it for 10 to 40 perceft in 28 days.

7. It can also save cement with the reduction of its amount at 7 to 25 percent and can maintain the same 

8. It can improve the density of concrete and reduce the shrink and creep and at the same time improve the durability to improve its service life.

■ High concentration product,the general recommended dosage powder is 0.4 to 1.0 percent. Generally the liquid is 1.0 to 2.5 percent. Low concentra-tion product, the general recommended dosage powder is 0.5 to 

1.2 percent. Generally the liquid is 1.2 to 3.0 percent.
