YL-SNF-C(Na2SO4 less than 18%) Sodium Naphthalene Sulfonate Formaldehyde This product, named -naphthalene sulfonate formaldehyde condensate, is non-air entraining superplasticizer. It has good dispersing performance to the cement particles. Compared with traditional plasticizer, it has higher water reducing rate, and good for preparing mass concrete, fresh concrete required for early strength and high strength, and precast concrete and parts. It also has good adaptability to commonly used cement, and widely used in roads, bridges, dams, power engineering, civil construction, steam and natural curing precast parts and other projects. Advantage: * Higher water reducing rate. By the recommended dosage, the water reducingrate can reach 15% -20%. * Improve the workability of concrete, such as compression, long-term strength, flowability, etc., and enhance the reinforcement of steel and concrete. * Reduce costs. In the case of maintaining the same workability and strength, cement amountcan be reduced. * Wide adaptability, cost-effective. Good adaptability to all kinds of cement, such as Portland cement, slag cement, volcanic ash cement, etc. * Be mother material to formulate other admixtures.(like early strength, set retarder, pumping agent, antifreezing agent).

Joyreach Fdn Powder Naphthalene Water Reducing Admixture Superplasticizer for Concrete Package 25kg/50kg Naphthalene superplasticizer has good adaptability to various cements and improves the operability of concrete.FDN has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete. It is widely used in concrete engineering: highway, railway, bridge, tunnel, power station, dam, high-rise building and other projects.It has good dispersion, water reduction and early-strength effect.Adding naphthalene series superplasticizer into ordinary concrete can improve the physical and chemical properties of concrete, improve the concrete strength, construction speed, project quality, technology and working conditions. 1. early strength admixture - improve construction progress; 2. retarding admixture - prevent cracking of large infrastructure such as airports and bridges; 3. pumping type admixture - transported by pump, such as high-rise buildings; 4. antifreeze admixture - used for winter construction. FDN-A High concentration product with sodium sulfate content no more than 5 percent. FDN-AI Middle concentration product with sodium sulfate content no more than 10 percent. FDN-AII Low concentration product with sodium sulfate content no more than 18 percent. FDN-23 sodium sulfate content no more than 23 percent,cheapest type to save cost. Usage method: --Powder 0.5%-1.0%, recommended dosage 0.75%; --Liquid is 1.0%-2.0%, and the recommended mixing amount is 1.5%. The mixing amount can be appropriately increased according to the grade of concrete. --Each batch of goods must be tested to meet the engineering requirements before use. 1. As the requirement of engineer,the dosage can be adjusted after testing. 2. It can be put into blender with mixing water,making mixing before concrete pouring,the plasticizing effect could be better.

Naphthalene Sulfonate Formaldehyde Condensate (SNF), also known as Poly Naphthalene Sulfonate (PNS) and Formaldehyde Sulfonate Condensate (FDN), is a highly effective water reducer and superplasticizer commonly used in the construction industry to improve the workability and strength of concrete.

1,Blend dosage range is 0.5-1.2%. Appropriate blend dosage can be selected according to project object and the materials used during application. 2,FDN powder is recommended to be applied in solution. It can be used in dry form, but make sure mix it thoroughly with concrete. 3,If this product is applied with adoption of stagnant water blending method or post-blend approach, water reduction and dispersion will be better. 4,This product can be formulated with concrete additives of other varieties. It can be "double blended" with blending materials such as fly ash, ground slag, etc. But the blend dosage shall be calculated based on the total of cementing materials. 5,When this product is used for the first time or cement variety is changed, concrete trial preparation shall be conducted according to the adopted materials and construction requirements in the field. Construction mixing rate shall be adjusted based on testing result to serve as instruction for construction blending.
