Description Naphthalene Sulfonate (UNF-5) concrete admixture, a high range water reducer with no air entraining, is commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. Naphthalene Sulfonate (UNF-5) concrete admixture is made of naphthalene, sulfonic acid, formaldehyde and alkali through sulphuration, hydrolyzation, condensation and neutralization reaction. Naphthalene Sulfonate (UNF-5) concrete admixture contains no chloride. It complies with chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017. Application 1.Naphthalene Sulfonate (UNF-5) concrete admixture is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement. When concrete added this superplasticizer needs to be steam cured, it requires considerable structural strength. The curing requirements should be pre-tested. 2.Naphthalene Sulfonate (UNF-5) concrete admixture is applicable in areas with the daily lowest temperature of and for making concrete which requires high fluidity, high strength or steam curing. 3.Naphthalene Sulfonate (UNF-5) concrete admixture can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm. 4.Naphthalene Sulfonate (UNF-5) concrete admixture could be used as a raw material together with other components to make other kinds of admixtures, such as accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures. 5. Naphthalene Sulfonate (UNF-5) concrete admixture will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired. 6. Naphthalene Sulfonate (UNF-5) concrete admixture is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc. Features and Benefits 1. High water reducing rate: It has remarkable dispersion and water reducing effect. Its water reducing rate is over 20%. 2. High slump flowability and strength: It enhances the miscibility, fluidity and smoothness of concrete at a regular water/cement ratio and improves the bond stress between concrete and steel bars. 3. Saving cement: It may save cement by 12-25% without sacrificing slump retention and strength. 4. Early Strength and Strengthening Ability: It improves the compressive strength of concrete at same cement quantity and slump loss. 5. Great Compatibility: Naphthalene Sulfonate (UNF-5) concrete admixture can be added to a variety of concrete and improves the physical and mechanical functions of it. By reducing the heat of concrete hydration, it significantly enhances the impermeability of concrete. 6. Improved Compactness: Naphthalene Sulfonate (UNF-5) concrete admixture develops a better pore structure and makes the concrete more compact. It produces high durable concrete of which the anti-infiltrating index is beyond P18. Uses and Dosages 1. Prepare solutions as required. 2. Naphthalene Sulfonate (UNF-5) concrete admixture can be added directly or added in after being dissolved into water. It can be added during mixing and after mixing. The afterward approach can achieve better result. 3. The agent can be combined with other externally applied agents if compatibility test is satisfied. 4. When Naphthalene Sulfonate (UNF-5) concrete admixture is applied in the form of powder, normal dosage ranges from 0.5% to 1.0% of the weight of cementitious material in 1m3 of concrete, while the suggested rate is 0.75% considering technical and economic factors. Package, Storage & Handling 1. Naphthalene Sulfonate (UNF-5) concrete admixture for powder: Woven fabric bag with plastic liner. Net weight: 25kg +/- 0.13 kg. 2. When being handled or stored, special care should be taken to broken package, humidity and moisture to avoid consolidating. If it consolidated, please dry, shatter, then sift it through 0.63mm apertures or make solution before using. 3. Naphthalene Sulfonate (UNF-5) concrete admixture should be stored in a dedicated warehouse that is well-ventilated and dry. It remains effective in one year. 4. Since Naphthalene Sulfonate (UNF-5) concrete admixture is packed in woven plastic bags, though the product is nonflammable, cautions should be taken to avoid fire. 25kg/bag, 15 tons loaded in a 20ft container.
