Product Description

The naphthalene series high-efficiency retardant water-reducing agent has a high water-reducing rate, good fluidity, slight slump loss over time, and no segregation or bleeding. Meanwhile, it can significantly improve the fluidity and strength of concrete at all ages, especially the later potency, which has a significant enhancement effect. It is the first choice for admixture for high-strength concrete, commercial concrete, earthquake-proof concrete, self-leveling grouting materials, and other products.

range of application:
1. Suitable for concrete constructed under hot temperature conditions, such as large-volume concrete, and cast-in-place piles;
2. Suitable for sliding form constructed concrete, pumping concrete, and fly ash concrete;
3. Can be configured with various grades of concrete from C15 to C45.



 

Model	Solid Content	Sodium Sulfate Content	Fluidity Of Cement Slurry	Water-Reducing Rate
SNF-5	≥91	≤5%	≥200	≥18
SNF-18	≥91	≤18%	≥180	≥16

Performance features:
1. The product is non-toxic, non-flammable, stable in shape, and has no corrosion effect on steel bars;
2. The air content is 2.5-4.0%, which is conducive to pumping construction;
3. The sodium sulfate content is ≤18% with low alkali content, and it will not cause an alkali-aggregate reaction;
4. The water-reducing rate is 12-20%, which can increase the fluidity of the mixture, and the concrete slump reaches 15-20cm; the loss in 60 minutes is ≤20mm, which is suitable for the continuous pouring of large volumes of concrete in hot seasons, reducing hydration heat and reducing the temperature stress to avoid the occurrence of temperature difference cracks;
5. Increase the compactness of concrete, reduce shrinkage, improve the durability of concrete, and extend its service life.
The disadvantage of the naphthalene series superplasticizer is poor slump retention performance. However, mixed with retarders (sodium tripolyphosphate, sodium citrate, potassium sodium tartrate, sodium gluconate, and sucrose) can reduce slump loss. It can also be compounded with lignin sulfonate to maintain certain air entrainment and reduce concrete slump loss.
