Product Description

Water Reducing Agent
Naphthalene-based Superplasticizer

Chemical Nature

The naphthalene Superplasticizer 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 stage strength, which has a significant enhancement effect. It is the first choice for admixture for high-strength concrete, commercial concrete, self-leveling grouting materials, and other products.
 

Typical Properties

 

Type	SNF-5	SNF-18
Solid content	≥91	≥91
Sodium sulfate content	≤5%	≤18%
Fluidity of cement slurry	≥200	≥180
Water-reducing rate	≥18	≥16
PH	8±1	8±1
Chloridion	≤0.5	≤0.5

Features of application

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%, the alkali content is low, 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 of concrete 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 outstanding disadvantage of naphthalene-based high-efficiency water-reducing agent is its poor slump retention performance. It can be mixed with retarders (sodium tripolyphosphate, sodium citrate, potassium sodium tartrate, sodium gluconate) to reduce slump loss. It can also be compounded with lignin sulfonate to maintain certain air entrainment and reduce concrete slump loss.

 

Usage

Pre-mix evenly with other dry powder components before packaging. Mix and use on-site according to the recommended amount of water.
The recommended addition amount is 0.01%-0.30% of the cementitious material, which must be pre-tested according to the raw materials and construction specifications before use.

Packaging

25 kg / 55 lb paper bag
 

Storage condition

Store products with original packaging in a dry, clean environment and away from heat sources. This product is not easy to lose efficacy, but it is hydrophilic-based. If the storage environment is poor, it will slowly absorb moisture. It is recommended to follow the first-in-first-out principle when using it. The packaging must be tightly sealed to prevent moisture intrusion if not finished use.

Product safety

According to the legal provisions on dangerous goods and preparations, this product is non-hazardous. Avoid dust formation and accumulation. Scattered effects should be swept up while keeping them dry. Touching with water will cause a risk of slipping. Contact us for further information.
