Product description

JK-02NP High Range Water Reducing Concrete Admixture Superplasticizer ASTM C494, Type F, ASTM C 1017 Sodium Naphthalene Sulfonate Formaldehyde (Na2SO4≤18%)   Product Description   JK-02NP 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-02NP contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. It complies with ASTM Designation C494, Type F, ASTM C 1017, GB8076-2008 and GB50119-2003 etc.   Uses Ø Produces the high slump flowing concrete with no loss in strength. Ø Produces low water/cement ratio concrete with high strengths. Ø Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete, prestressed concrete etc. where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation. Ø Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.)    Advantages   Ø Substantial improvement in workability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improved density and surface finish. Ø High water reducing rate. 40% increase in 28 day strengths. High strengths after 8 hours. Ø Compatible with Portland cement, Normal Portland cement, Portland Slag Cement, Flyash Cement, Portland Pozzolanic Cement, etc. Ø Improve workability (slump) of concrete when added into mixing truck.     Specification

  Dosage   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-02NP 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.   Technical Data Sheet
