Sodium Naphthalene Sulfonate Formaldehyde

YL-SNF-A High Range Water Reducing Concrete Admixture (High Concentration)
Superplasticizer ASTM C**4, Type F
Sodium Naphthalene Sulfonate Formaldehyde (Na₂SO₄≤5%)

Description
YL-SNF-A is a high range water reducer and high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc.

YL-SNF-A (Na₂SO₄≤5%) contains no chloride and is non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. Thus, it meets the requirements of chemical admixture specifications for concrete, complying with ASTM C **4, Type F. ASTM C ***7, GB********8 and GB*********3 etc.

Uses

YL-SNF-A has no retarding and no air-introducing. It is characterized as good superplasticing performance, high water-reducing rate and high strength with low dosage. It has no chloride, low alkali content, low sulphonate and high purity. This product is easy to use and can be widely used in different concretes.
YL-SNF-A can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as zero centigrade degree. In steam curing, concrete with superplasticizer has to be strong enough before heating. The steam curing specification has to be pre-tested. It is particularly used as base material for compound admixtures.

Advantages

High water-reducing rate: YL-SNF-A can reduce water ****0%. It has features of superplasticizer, effectively increases concrete fluidity and reduces water penetration and segregation and improves the encapsulation force of the concrete with reinforcing steel bar.
Strengthening: Given the same amount of cement and slump requirement, this product with the dosage 0.**1.2% can increase the concrete early strength and reinforced effect by *****0%, ****0%, ****0% and ****0% on day 1, 3, 7, and *8 respectively.
High applicability: It can be used in variety of cement and is compatible with other admixtures.
Low sodium Sulfate content: The aqueous solution has no crystals in winter, which can avoid pipeline congestions when being used. It is suitable for automatic working.
Effective durability: It can modify the structure of concrete and increase the property of anti-seepage, anti-freezing, and carbonization.
Easy to use: It can be added directly or used after dissolved in water, and also can be used for different working condition and concrete mixer.

Dosage
0.**1.2% by weight of cement. Exact dosage rates depend on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.

YL-SNF-A can be added directly or added in after dissolved in water. It can be added during mixing and after-mixing (better). The after-mixing approach can achieve better result.
