Product Description
JK-01NPisa high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS and FDN etc.
JK-01NP (Na2SO4≤5%) contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. Thus, it meets the requirements of chemical concrete admixture specifications: comply with ASTM C 494, Type F. ASTM C 1017, GB8076-2008 and GB50119-2003 etc.
Uses
- JK-01NP 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-01NP can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as 0°Cdegrees.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.
- It can prevent from the alkali-aggregate reaction because of the biggish alkali reactivity of aggregate or the alkali-aggregate reaction in the moist environment.
Advantage
- High water-reducing rate: JK-01NP can reduce water 20-30%. 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 0.5-1.2% can increase the concrete early strength and reinforced effect by 50-100%, 40-70%, 25-60% and 20-60% on day 1, 3, 7, and 28 respectively.
- High applicability: It can be used with different variety of cement. It is compatible with other admixtures.
- Low sodium Sulfate content: The aqueous solution has no crystals in winter, which can avoid pipeline congestions when JK-01 NP applied. 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. It can be used for different working condition and concrete mixer.

Dosage
0.5-1.2% 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-01NP 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.application for concrete admixture formulations, high strength and low cement input,economical concrete additive material
