Concrete Sodium Naphthalene Sulfonate Formaldehyde For Concrete Admixture/ SNF Powder Water-Reducing Agent

Concrete Admixture Sodium Naphthalene Sulfonate Product Description:

The naphthalene-based superplasticizer is a non-air-entraining high-efficiency water reducing agent synthesized by the chemical industry. Chemical name Naphthalene sulfonate formaldehyde condensate, which has strong cement particle dispersibility. Naphthalene-based high-efficiency water reducer can be divided into high-concentration products (Na2SO4 content <5%), medium-concentrated products (Na2SO4 content 5%-10%) and low-concentration products (Na2SO4 content >18%) according to the content of Na2SO4 in its products. At present, most naphthalene-based super plasticizers have the ability to control the Na2SO4 content below 3%, and some advanced companies can even control it below 0.4%.

Chemical Uses:

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.

Advantages:

1. SNF produces high slump flowable concrete with no loss in strength.
2. SNF produces low water/cement ratio concrete and therefore, high strengths.
3. SNF in prestress/precast work, can be used to substantially reduce or eliminate the high energy requirements of external heat for accelerated curing.
4. SNF concrete, even at high slump, exhibits no significant segregation in comparison to concrete without a super-plasticizer at the same slump.
5. SNF aids in rapid discharge of concrete from truck mixers thereby reducing on the job time and improving mixer utilization.
