High Range Water Reducing Concrete Admixture
Naphthalene Superplasticizer ASTM C494, Type F
JK-02NP SNF-C Sodium Naphthalene Sulfonate(Na2SO4≤18%)
Description
JK-02NP SNF-C Sodium Naphthalene Sulfonate(Na2SO4≤18%) 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.
Uses
Produces the high slump flowing concrete with no loss in strength.Produces low water/cement ratio concrete with high strengths.
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.
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.)
