JK-SNF-A is a naphthalene-based highly effective water reducing agent for promoting accelerated early and ultimate strength development, commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc.
JK-SNF-A possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength enhancing. It has no chloride, low alkali content, low sulphonate, and high purity. It can be widely used in different concretes with less dosage and easy to use.
JK-SNF-A can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as 0ºCdegrees. 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.

0.5-1.5% by weight of cement. Exact dosage rates are dependent 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.
JK-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.
