Description JK-01NP is a 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 admixture specifications for concrete: comply with ASTM C 494, Type F. ASTM C 1017, GB8076-2008 and GB50119-2003 etc. Uses 1. 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. 2. JK-01NP can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as zero centigrade 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. 3. 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.
