naphthalene sulfonate formald

Brand:yuansheng

Description:The naphthalene superplasticizer is a chemically synthesized non-air-entrained superplaaticizer,with chemical name of naphthalene sulfonate formaldehyde concrete condensate.it has strong dispersant effect on cement parrticles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast member with early strenth and high strength requirements,can comprehensively improve various properties of the concrete,and is widely applied to highway ,bridges,dams,harbors,tunnels,electric power,water conservancy as well as industrial and civil architecture ,steam-cured and naturally-cured precast members and so on.

Product detail:

Sodium naphthalene sulfonate for concrete contain 5%, 10%, 18% three different specifications due to different sodium sulphate content. Because of its stable performance, non-poisonous, odorless, non-flammable, non-corrosive to steel bars and much better than sodium ligno and calcium ligno 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.

 

Feature:

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 and water reducing ratio 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.
