Description

YL-SNF-AHigh 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 andhigh 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 isnon-corrosive to steel bars,non-poisonous, odorless, andnon-flammable. Thus, it meets the requirements of chemical admixture specifications for concrete, complying withASTM C **4, Type F. ASTM C ***7, GB****-***8 and GB*********3 etc.
 
Uses

• YL-SNF-Ahasno retarding and no air-introducing. It is characterized as good superplasticing performance, high water-reducingrateandhighstrength with low dosage. It hasno 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 aszerocentigrade 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.

• 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 theencapsulation forceof the concrete withreinforcing steel bar.
• Strengthening: Given the same amount of cement and slump requirement, this productwith the dosage 0.**1.2%can increase the concrete earlystrength andreinforcedeffect by ***100%, **-70%,*5-60% and **-60% on day 1, 3, 7, and *8 respectively.
• High applicability: It can be usedin 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. Itissuitable 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.
